When the thickness of asbestos board reaches 30 mm, the shell temperature could be controlled below 360 ℃, which is lower than the creep temperature of the shell material, and the thermal expansion stress of the shell is only 50% of that without asbestos board.

当石棉板厚度为30mm左右时，炉壳温度可以控制在360℃以下；低于炉壳材质的蠕变温度，炉壳所受到的热膨胀应力仅为没加石棉板时的50%。

Ltd. The calculation indicates that converter heat insulation layer thickness of asbestos board is about 30 mm. The converter shell temperature can be controlled within 360 ℃, which is lower than the creep temperature of shell material.

对重钢50t转炉进行了炉壳（炉身段）温度场分析，计算表明：转炉隔热层石棉板的厚度为30mm时，炉壳温度就能控制在360℃以内，低于炉壳材质的蠕变温度。

The main cause of deformation of a converter shell is temperature rising of the converter shell, a economical and effective method to reduce the temperature and creep deformation is adopting a heat insulation layer of asbestos board.

转炉炉壳温度升高是炉壳变形的主要原因，采用内衬石棉板隔热是降低中小型转炉炉壳温度、减轻炉壳蠕变变形的经济有效措施之一。
