Recently a lot of customer consultation crusher jaw plate, but customers to hubei board what use material and heat treatment process is poorly understood, today will give you a detailed introduction of the practical application of crusher jaw plate.
Jaw crusher moving SHANVIM works for music: motor drive belt and pulley, make through eccentric shaft dynamic jaw movement up and down, when moving jaw rises between the bracket and fixed jaw Angle, so as to promote dynamic jaw plate to the fixed jaw close, rather than the material being crushed or broken at the same time, achieve the purpose of broken; When the jaw goes down, the Angle between the bracket and the jaw is smaller, and the moving jaw plate is removed from the fixed jaw plate under the action of the pull rod and spring, and the broken material is discharged from the lower part of the broken cavity. With the continuous rotation of the motor, the broken motor jaw is crushed and discharged, and the mass production is realized.
The jaw crusher is the main part of the jaw crusher. According to the different type of jaw crusher, there are various sizes, which are made of high manganese steel. There have been 100 years of history, high manganese steel under the condition of strong impact abrasive wear, high manganese steel has excellent anti-wear performance, reason often used in mining, building materials, coal and other mechanical equipment, applicable materials: coal gangue, feldspar, barite, basalt stone, basalt stone, basalt stone or other materials. Under the condition of low impact condition, the effect of hardening is not obvious, and high manganese steel can not play the characteristics of materials.
It is found that three factors influence the abrasion resistance, material, raw material and heat treatment process. The material is the basic factor that decides the wear-resisting degree of the steel jaw, and the high steel can directly increase the wear resistance of high steel, namely Mn13Cr2. The use of raw materials, high waste of fierce steel use shall not exceed 50%, because of the high waste of fierce steel will be harmful to the sulfur and phosphorus into the new cast of hubei board, affect the service life of jaw plate. Last high fierce heat treatment process of steel plate of hubei, low temperatures heat up too fast will result in the crack of the jaw plate, therefore, the correct operation is below 350 ℃, temperature < 80 ℃ / h under 750 ℃, < 100 ℃ / h, and have different periods of heat preservation. To > 750 ℃, the castings in plastic state, can quickly heat up. The insulation time (usually 1 hour /25mm) shall be determined according to the thickness of the castings to 1050. And then quickly rose to about 1100 ℃ heat preservation and a half hours. After casting, the casting must be in water as soon as possible. The time of entering water should not exceed 45 seconds, and the winter time should be shorter. The temperature rise is too slow, the heat insulation time is too short, and the time interval between the oven and the water intake is too long (not >0.5min), all of which affect the quality of the high steel plate.
