钢锭液心加热和轧制,是在钢锭心部存在一定数量未凝固的钢液条件下进行加热与轧制。我公司曾在1975、1982、1983年共进行过53罐钢锭液心加热和轧制试验,证明此种工艺有许多优点。1984年4～9月又进行了29罐试验。在此基础上,1985年4季度至1986年8月试验生 Steel ingot heart heating and rolling, is the heart of the ingot in the presence of a certain number of non-solidified steel under the conditions of heating and rolling. Our company conducted a total of 53 tank ingot liquid heart-warming and rolling tests in 1975, 1982, and 1983 to prove that the process has many advantages. From April to September 1984, another 29 cans of tests were conducted. On this basis, the fourth quarter of 1985 to August 1986 pilot students
