为了貫彻大、中、小型企业同时并举的方針,我們曾协助綦江县赶冰銅厂进行土法煉銅試驗,从1958年第一季度开始到9月中旬,先后經过120次試验,在该县、区、厂党組织的正确领导下,在爐型、配料、操作等各方面作了改进后,终于取得了在小土鼓风爐中連續生产冰銅的初步成功。小土鼓风爐的优点: (一)投資省、建爐快: 建成时間5～6个石工,工作2天; 投資:工人工资12～16元,材料全用天然砂石,上山开采,不花成本; (二)完全是土法,除风箱外(人力、水力、獸力均可),无任何附属设备,因此可以遍地开花; (三)能連續生产冰銅: (四)爐子寿命:泡砂石砌爐5～7天/爐24小时連續生产,白砂石砌爐20天/24小时以上連續生产。 (五)結構简单易造,爐日处量可随风量加大俱增。小土鼓风爐适用范圍:
In order to carry out the principle that large, medium and small-sized enterprises should simultaneously implement both, we have assisted Qiantang Copper Mine to carry out indigenous copper refining tests from the first quarter of 1958 to mid-September. After 120 tests, Under the correct leadership of the county, district and factory party organizations, the initial success of continuous production of matte in a small soil blast furnace was finally achieved after improvements were made in the furnace type, ingredients and operation. The advantages of small soil blast furnace: (A) investment in the province, built furnace fast: the completion of time 5 to 6 masonry, work 2 days; investment: workers wages 12 to 16 yuan, the material used in all natural gravel mining up the mountain, (2) completely native law, except bellows (human, hydraulic, animal power can be), without any ancillary equipment, so you can blossom everywhere; (C) the continuous production of matte: (D) furnace life: Bubble sand stone furnace 5 ~ 7 days / 24 hours continuous production furnace, sand stone furnace 20 days / 24 hours continuous production. (E) the structure is simple and easy to create, the amount of the furnace can be increased with the amount of wind all increase. Small soil blast furnace Scope of application:
