The preventive measures for the harmful defects of alkali metals are as follows: 1, reducing the alkali metals content in the raw materials; 2, increasing the MgO content of the sinter , decreasing the basicity of slag , decreasing the Si content of the pig iron, increasing relative slag volume; 3 , introducing prereduced ore pellets or partly reducted sinter; 4increasing the ability of coke resisting alkali metals; 5, using refractories that have the ability of resisting corrasion of alkali metals; 6 , cleaning the blast furnace periodically. The above recommendations are necessary for decreasing the circulation and accumulation of alkali metals effectively in blast furnace, reducing the harmful influence of alkali metals on blast furnace, increasing the smelting intensity, decreasing the coke rate, improving the gas permeability.

Grisea have been obtained in recent years as well.In our previous work, an RIL population consisting of 304 lines was constructed from the indica cross Zhong 156/Gumei 2. Two genes conferring complete resistance to blast isolate 92-183 (ZC15) were primarily mapped by using 148 lines of the population. In the present study, genotype of the 304 RILs were analyzed and QTL mapping for partial resistance to 2 isolates of leaf blast and 1 isolate of neck blast were conducted.
