trolley type annealing furnace maintenance skills

The trolley annealing furnace is the national standard energy-saving cycle trolley electric furnace, which is mainly used for high chromium and high manganese steel castings, grey cast iron pieces, ductile cast iron pieces, rollers, steel balls, crusher hammer head, wear-resisting lining plate quenching, annealing, aging and heat treatment of various mechanical parts. Here is a brief analysis of the trolley type annealing furnace maintenance skills:

Car type annealing furnace is made of high quality high temperature resistant fiber and energy saving brick of living the county modules, high-quality energy-saving lining heating elements with high temperature resistance alloy flat belt, service life for up to 5 years, adopting back connecting rod sealing mechanism automatically, sealed performance is reliable, the furnace gas is not easy to leak, thus saving energy consumption, ensure that the furnace temperature and temperature field are consistent, microcomputer automatic program control system, can automatically complete the heat treatment process curve, control of high temperature.

During the regular maintenance of Huahui type trolley annealing furnace, pay attention to the fact that the resistance wire, if used, should not collide and bend, so as not to break. Electric furnace motor needs regular inspection, add lubricating oil and so on, pay attention to the safety of use. The shaft sleeve must always be checked for lubricating oil to prevent damage to the shaft sleeve due to lack of oil. Check the use of heating elements regularly. After a short period of use, the heating element shall not bend or collide. If not severe corrosion and broken, can use the same material as the electric furnace wire (or the electric furnace wire itself) as a welding rod, using acetylene gas for heating welding, welding rod USES 50% white cloud powder mixed, if the high temperature fan heating element severe corrosion can not be used, it should be replaced.

Check the usage of the trolley furnace instrument and thermocouple regularly to prevent the inaccuracy of temperature measurement due to the error of the instrument and thermocouple. The workpiece with corrosive, volatile and explosive gas is forbidden to enter the furnace body of trolley, so as not to affect the service life of heating element and refractory and cause explosion and other accidents. Trolley furnace must not run over temperature, otherwise it will shorten the service life of the equipment. Too many workpieces need to be cleaned before entering the furnace, steel wire brush can be used. The workpieces should be stacked evenly, about 100-150mm away from the heating element.

Brutal operation is strictly prohibited, the workpiece should be put lightly, avoid impact. When electric furnace is used, operator must not leave post without authorization, the working condition that must notice trolley type annealing furnace at any time is normal.
