我国中、小型钢铁厂的铸铁机,多数是滚轮移动式的,上、下层链带均按同一倾角直线运行,其倾角大小各不相同,多数小于铁模倾角,铁模则大同小异,容积利用系数一般只有1/2左右。 我厂30m双带滚轮移动式铸铁机,改造前如图1所示。铁模断面如图2,其倾角β为8.3°。可是按此设计的铸铁机,每炉的铁水浪费多达1t以上,由此而来的“板板铁”堆积如山,造成很大浪费。 China’s iron and steel mills in small and medium-sized steel mills, the majority of the wheel-type mobile, the upper and lower straps run at the same inclination of a straight line, the angle of the different sizes, most less than iron angle, iron molds are more or less the same volume utilization factor Generally only about 1/2. I plant 30m double with a roller mobile cast iron machine, before the transformation shown in Figure 1. Iron mold section shown in Figure 2, the inclination β is 8.3 °. However, according to this design of cast iron machine, each furnace of hot metal waste as much as 1t, resulting from the “plate iron” piled up, resulting in a great waste.
