烟台耐火材料厂主要产品是各种粘土質耐火砖和矽砖,所用原料有石英石、熟凡土、焦宝石、坊子土。二氧化矽含量最高的占98%以上,平均亦在46%左右。該厂粉碎車間共有干碾机10台,1959年前完全是敝露式的生产,車間內粉尘弥漫,經测定粉尘浓度平均在350毫克/米~3左右。工人戴紗布口罩工作2—3小时后,口、鼻內都塞滿了灰尘。从1959年后该厂采取了土法先上馬,土洋結合,就地取材的办法利用耐火砖将大碾全部进行了封閉。結果使車間卫生面貌起了根本的改变,使粉尘浓度,基本上达到了国家規定允許浓度2毫克/米~3。同时由于安装了提升机和固定斜篩,自动出料攪拌流水作业綫,大大減輕了劳动强度,节約了劳动力,鼓舞了工人的干劲,提高了生产效率,并荣获了全国冶金系統防尘工作五大紅旗之一。
Yantai refractory plant main products are all kinds of clay brick and silica bricks, the raw materials used quartz, cooked soil, coke stones, Fangzi soil. The highest content of silica accounted for more than 98%, an average of about 46%. The plant crushing plant a total of 10 dry-running machine, completely unmasked 1959 production, the workshop filled with dust, the measured dust concentration on the average 350 mg / m ~ 3 or so. Workers wearing gauze masks work 2-3 hours after the mouth, nose are stuffed with dust. From 1959 after the plant has taken the first law of the Turkish soil, the combination of earth and land, the use of local methods of using refractory bricks will be closed all the big grind. As a result, the surface appearance of the workshop has fundamentally changed so that the dust concentration basically meets the national allowable concentration of 2 mg / m ~ 3. At the same time as a result of the installation of elevators and fixed oblique sieve, automatic discharge of mixing flow line, greatly reducing labor intensity, saving labor, encouraging the workers’ efforts to improve production efficiency and won the national metallurgical system dust work One of the five red flags.
