为了减少盐浴表面的辐射热损失,我们选用了多种覆盖材料在中温和高温炉中进行反复试验,找出了稻草灰这种比较理想的覆盖材料。现将我们在300×300mm中温盐浴炉上试验和使用的情况介绍如下。1.稻草灰覆盖层的形成
In order to reduce the radiation heat loss on the surface of the salt bath, we used a variety of coating materials in a moderate temperature and high temperature furnace to conduct repeated tests to identify the straw ash is the ideal covering material. Now we in 300 × 300mm medium temperature salt bath test and the use of the situation are described below. 1. straw ash cover formation
