目前，国内大、中型钢锭模的生产主要还是采用粘土砂，而树脂砂在钢锭模上的应用还很少。主要原因是树脂砂生产成本高，而且对于钢锭模之类的厚大件，树脂砂耐高温性相对较差，易过导演散，不耐高温铁水长时间冲刷等缺点，长期未找到合适的解决方法。树脂砂结后均衡凝固理论生 At present, the domestic production of large and medium-sized steel ingot mold is mainly the use of clay sand, and resin sand in the ingot mold on the application is still small. The main reason is the resin sand production costs are high, but also for the ingot mold like thick pieces of resin sand is relatively poor high temperature resistance, easy to lead the director scattered, not resistant to high temperature hot metal washing a long time and other shortcomings, long-term did not find a suitable solution method.
