硫化机材质属灰口铸铁,长期使用后易产生穿透性裂纹,欲需焊补其裂纹,则由该机特点所定,需相应的焊补工艺,确保其焊补质量。我矿硫化机是利用蒸汽温度作为溶化胶的,它的额定蒸汽压为7kg/cm~2、温度164℃具有高温高压特点,因此当对其硫化机之裂纹焊补时,因高温高压对其焊接应力的破坏及密度的扩展性影响都很大,所以焊补时对强度及致密性要求均较高,我们对该机的焊补采用了以下工艺,收到了一定效果。
Curing machine is made of gray cast iron, long-term use of easy to produce after the penetration of cracks, want to repair their cracks, the characteristics of the machine set, the corresponding welding repair process to ensure that the welding quality. I mine sulfide machine is the use of steam temperature as a melting gum, its rated vapor pressure of 7kg / cm ~ 2, the temperature 164 ℃ with high temperature and pressure characteristics, so when the vulcanizing machine crack welding fill due to its high temperature and pressure on its Welding stress and the destruction of the expansion of the impact of density are large, so when the welding on the strength and tightness are higher, we use the following welding welding machine, received a certain effect.
