In order to guarantee the engineering quality of coking furnace, some measurements should be taken to control the line size of coking furnace and datum mark,and to check up the ver-ticality and leveling, and to clean the expand gap of the coking furnace shaft hole, and to ensure saturation of mortar paste, and etc.

The stabilizing agent of water quality especially for the corrosion and incrustation is developed out through test for the water circulation system of blast furnace body.

3 BF furnace body was analyzed,and the refom experience of furnace body cooling system was summarized in Angang.

Starting from elongating the working life of the coke oven, this paper analyzes and sums up the coking techniques, probes into the reasons of influencing the working life of the oven body, and puts forward some corresponding preventive measures.

Spring support structure for furnace of low pressure casting machine and its propeties are devoted in the article which also illustrates the basis and the key points of design as well as its applicaion effect.

The article introduces principle and features of induction heating and structure of furnace particularly analyzes manufacturing engineering of induction_heated furnace.
