我厂铸钢车间碾砂工部为制备芯型砂,备有S116混砂机4台,S115碾砂机1台,分别承担铸钢件面砂与背砂及其它芯砂的碾压任务,由于水玻璃砂用量大,贮存性较差,混砂机的高峰负荷比较集中,因而比较忙乱,且加添各种原材料是凭经验控制,因此每台混砂机尽管配有专人掌握加料、卸料及碾压各程序,但仍然存在着定量定时不准,忙闲不均,型砂质量波动。由于型砂性能不稳定,造成铸钢件砂废较多,铸件质量波动,且劳动强度
I plant cast steel shop grinding department for the preparation of core sand, equipped with S116 Sand Mixer 4, S115 Sand Mill 1, respectively, to undertake the cast steel sand and the back sand and other core sand rolling task, due to Due to the large amount of sodium silicate sand and poor storage property, the peak load of the sand mixer is relatively concentrated, which makes it more hectic and adds a variety of raw materials which are controlled by experience. Therefore, although each sand mixer is equipped with manpower to handle feeding, discharging and Rolling the various procedures, but there are still quantitative timing is not allowed, leisure time, sand quality fluctuations. Due to the instability of the sand, resulting in more steel castings sand, casting quality fluctuations, and labor intensity
