The main types of nickel copper sulphide and laterite nickel ore, 90 years as the world economy, accounting for 65% of nickel uses strong growth in demand for stainless steel, nickel demand level of about five years ago more than 4% annual growth forecast over the next five to 10 years, a growth rate of 3.5% a 4% nickel laterite iron smelting kiln is the key equipment of the rotary kiln process, ore after drying into the rotary kiln, rotary kiln heated to 800-1000 ℃ after the removal of ore surface water and water of crystallization and partial reduction of iron ore, nickel and cobalt oxide into the melting furnace. As a laterite nickel ore kiln lined with rotary equipment life span has a great association. Available kiln lined with brick masonry can also choose to do other refractory lining, but in recent years, with the improvement of construction methods and refractories research breakthroughs, began to use the rotary kiln refractory castable lining and one The length of the whole cast molding, the level of production quality, and rotary kiln lining material selection and construction technology, quality and construction process of combining method to do kiln lining.
