Description
Technical Field
The utility model relates to the field of smelting, in particular to a system for treating titanium concentrate by combining a rotary hearth furnace with an electric furnace.
Background
The titanium concentrate is used for preparing high titanium slag, titanium white, acid sludge, titanium tetrachloride and titanium sponge. The strength of titanium is high, and the highest tensile strength of pure titanium can reach 180 kg/mm < 2 >. Some steels are stronger than titanium alloys, but the specific strength (ratio of tensile strength to density) of titanium alloys exceeds that of high quality steels. The titanium alloy has good heat-resistant strength, low-temperature toughness and fracture toughness, so that the titanium alloy is widely used as aircraft engine parts and rocket and missile structural parts. Titanium alloys can also be used as fuel and oxidant tanks and high pressure vessels. Today, auto-rifle, mortar bed and backlashless gun tubes are made of titanium alloy. The petroleum industry is mainly concerned with various vessels, reactors, heat exchangers, distillation columns, pipes, pumps, valves, etc. Titanium can be used as an electrode and as a condenser for power stations and as an environmental pollution control device. Titanium-nickel shape memory alloys have been widely used in instruments and meters. Titanium is used in medical treatment as an artificial bone and as various appliances. Titanium is also a deoxidizer for steelmaking and a constituent of stainless steel and alloy steel. Titanium dioxide is a good raw material for pigments and paints. Titanium carbide and titanium (hydro) carbide are novel cemented carbide materials. Titanium nitride has a color similar to gold and is widely used in decoration. Titanium resources in China are rich in reserves, but mainly ilmenite, and rutile ore is less. The domestic ilmenite has the defects of low grade and high impurity content, and has low production rate, large three wastes and high production cost when being directly used for preparing metallic titanium and titanium white, and can not directly meet the requirement of the titanium white by the chlorination process on raw materials, so that the titanium white is often required to be pre-enriched into high-grade titanium-rich materials.
The production method of the titanium-rich material is divided into two main categories, namely a dry method and a wet method, and along with the daily prominence of environmental problems, the production method not only aims to improve the annual output of titanium products, but also has the problems of energy consumption and environmental pollution. The wet process has been basically eliminated because of complex process, high production cost and serious environmental pollution, the dry process produces high titanium slag, the titanium concentrate is directly reduced, the separation table iron and titanium are ground after the reduction, and the product titanium-rich material has good acid solubility and is suitable for being used as the raw material of the sulfuric acid process titanium white. However, the method has the defects of high reduction temperature, poor reduction atmosphere, low recovery rate of titanium and iron and low taste of titanium-rich materials.
