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。

The thermal conductivity of heat insulation materials, containing vacuum rubber board, asbestos board and quartz glass etc. was tested at different average temperature with RDL 1 automatic measuring apparatus made by ourselves.

用自行设计的RDL-1型物质热导率自动检测仪测试了真空橡胶板、石棉板等材料在不同温度下的热导率；

Asbestos board divided into asbestos insulation board, asbestos by rubber sheets, asbestos floor slab.

石棉板分为石棉保温板、石棉橡胶板、石棉水泥板。

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。
