Box-type muffle furnace is a commonly used high-temperature furnace, which is widely used in metal heating, sintering, annealing and other processes. cnc-horizontal-metal-band-sawing-machine-gz4265I(https://www.antsmachine.com/cnc-horizontal-metal-band-sawing-machine-gz4265.html)n order to ensure the accuracy and stability of the temperature in the furnace, it is very important to verify the box-type muffle furnace. This article will give a detailed introduction to the inspection records of box-type muffle furnaces.automatic-type-double-column-horizontal-metal-band-sawing-machine-gz4240 (https://www.antsmachine.com/automatic-type-double-column-horizontal-metal-band-sawing-machine-gz4240.html) Furnace door sealing performance verification The sealing performance of the furnace door is one of the important factors for the box-type muffle furnace to maintain temperature stability. The verification record should include the following: 1. Check whether the furnace door seal is intact and whether there are problems such as aging and cracking;automatic-type-double-column-horizontal-metal-band-sawing-machine-gz4240-1-5-meters-servo (https://www.antsmachine.com/automatic-type-double-column-horizontal-metal-band-sawing-machine-gz4240-1-5-meters-servo.html) ⒉. Make sure there is no obvious air leakage after the furnace door is closed; 3. Evaluate whether the sealing performance meets the requirements by observing whether there is obvious heat leakage around the furnace door.Alumina ceramic densely sintered(https://www.vacfurnace.com/technology-frontiers/alumina-ceramic-densely-sintered/)

The full hydrogen bell furnace equipment includes a furnace platform, an inner cover, a heating cover, and a cooling cover. The process of the full hydrogen bell furnace is as follows: at the beginning of annealing, the steel coils to be annealed are stacked on the bell furnace platform, the inner cover is hoisted, and the cold state sealing test is carried out on the furnace platform, the inner cover system and the hydrogen inlet valve, and the test is successful. Finally, put the heating mantle button on the stove and carry out nitrogen purging;HORIZONTAL MITRE BAND SAW MACHINE BS-85 When the nitrogen purge meets the conditions, replace the nitrogen in the inner cover with hydrogen; after the heating starts, select the heating curve according to different materials to control the temperature until the core temperature of the steel coil reaches the requirement; then remove the heating cover, and then hoist the cooling cover , using the surrounding ambient air to cool the inner cover through the fan on the cooling cover;HORIZONTAL MITRE BAND SAW MACHINE BS-115 When the thermocouple detects that the circulating atmosphere in the inner cover reaches the set temperature, the cooling cover fan stops running; after the temperature of the steel coil core reaches the set value, the cooling is completed, and the cooling cover is removed; then nitrogen is purged, The hydrogen in the inner cover is replaced, and the inner cover is removed; finally, the steel coil is lifted away, and a process is completed.Vacuum sintering of transparent ceramics After the production preparation is completed, the PLC will perform various media systems including water circulation, hydraulic system, protective gas and power supply, etc. After checking and judging that the safety system, measurement system and various hardware devices are working normally, issue a command to clamp the inner cover. After the inner cover is clamped, the control program will start each control program with a large time axis as a reference.Vacuum Heat Treatment of Fasteners

High-purity corundum furnace tube, while using its high-purity and high-temperature characteristics, we must follow the inherent characteristics of corundum material (relatively poor thermal shock resistance, not resistant to rapid cooling and rapid heating), and operate with caution during use. Operation will cause the furnace tube to burst. The reasons for the explosion of the furnace tube are analyzed as follows:CK6163 CK6180 CK6185 HEAVY DUTY HORIZONTAL FLAT BED CNC LATHE MACHINE 1. The temperature difference is too large 1. When using a high-temperature furnace tube, the heating and cooling speed is controlled at 5 degrees per minute, the slower the better. Rapid cooling and rapid heating is one of the main reasons for corundum furnace tube breakage, and the operating temperature should generally not exceed 1650°C;CK61100 CK61125 MULTI-FUNCTIONAL AND PRECISION METAL CNC FLAT-BED LATHE 2. Always keep the inside of the tube clean, clean the inner wall of the furnace tube in time after use, and do not leave some samples in the tube to avoid chemical reactions that may cause the corundum tube to crack;Analysis of carbon content on the surface of carburized parts 3. Do not exceed 150 degrees when setting out and sampling, and slowly advance from the edge to the center. High-temperature sample delivery and sampling are the main reasons for corundum tube breakage, so do not touch the high-temperature furnace tube with low-temperature objects;Precision carburizing heat treatment of gears se the furnace tube to break;

Heat treatment mesh belt furnace has been widely used in fasteners, bearings, transmission parts and other mechanical parts. With the improvement of the manufacturing technology level of mesh belt furnaces and the requirements of energy saving, the heating method of the third generation product of mesh belt furnaces - stick-type mesh belt furnaces has developed from heating by metal electric heating elements to heating by gas. The heat generation device of the electric heating mesh belt furnace usually adopts a radiant tube, which is composed of a metal outer tube and a built-in squirrel-cage heating element. Depending on the operating temperature, the material used in the radiant tube is also different.CS61/6250C SERIES UNIVERSAL LATHES The heating element with built-in squirrel-cage structure is composed of metal electric heating elements and corundum insulating ceramic sheets. The metal heating element is a resistance wire, and its commonly used materials are nickel-chromium alloy wire and iron-chromium-aluminum alloy wire. After the nickel-chromium alloy wire is heated in the air, a layer of hard Crz03 protective film is formed on the surface and adheres to the alloy substrate. The melting point is higher than that of the alloy substrate. It can withstand alternating heating and cooling and has strong corrosion resistance.C6163B UNIVERSAL LATHE The heat generation device of the gas heating mesh belt furnace is commonly known as the gas burner. For the convenience of use, maintenance and energy saving, the high-speed burner enables the fuel and the combustion-supporting air to be completely burned in the combustion chamber. Spray into the furnace at a high speed, strengthen the convective heat transfer to the workpiece, promote the circulation of the air flow in the furnace, and achieve the purpose of uniform furnace temperature and improved heating effect.Compound Gas Nitriding Treatment Process For Swing Arm Bogies The control of the gas burner is more complicated than that of the electric heating radiant tube. It needs to complete the flame detection in the furnace, automatic ignition control, gas supply control, combustion air control, etc. The combustion system adopts a ratio valve control method to make the gas/air ratio the best and reduce excess air.Compressor impeller vacuum heat treatment
