Abstract
The utility model provides a calcium oxide and calcium oxide contained refractory material with a laser-cladding surface layer. The calcium oxide and calcium oxide contained refractory material is characterized in that at least one laser-cladding surface layer is coated on the surface of a calcium oxide and calcium oxide contained refractory material base material; and a cladding material comes from the cladding of the surface of the base material. The calcium oxide and calcium oxide contained refractory material comprises a sintering refractory material and a sintering-free refractory material.
Description
Technical field
A kind of refractory material particularly has the calcium oxide of surface-treated layer and contains the calcium oxide series refractory material.
Background technology
In recent years, calcium oxide refractory material, especially magnesium calcium refractory material more and more receive common concern both domestic and external.This material has that good fire resistance, thermal shock resistance, alkali resistance slag and scum ability are strong, high-temperature vacuum is stable down, particularly at aspects such as cleaning molten steels, is to smelt special steel, the indispensable high-quality refractory material of clean steel.But this type refractory material is easy to the water reaction and then expands, and makes its range of application receive a lot of constraints.Want to make such refractory material to be used well and develop, just must solve the aquation problem.
At present, calcium oxide and the waterproof method that contains the calcium oxide series refractory material mainly contain methods such as vacuum sealed package, chemical surface treatment, immersion coating and adding additive.
But from practical effect, above-mentioned any method all can not tackle the problem at its root.
Summary of the invention
For this reason, the utility model provides a kind of and has the calcium oxide of laser melting coating superficial layer and contain the calcium oxide series refractory material.This refractory material not only can fundamentally solve calcium oxide and contain the aquation problem of calcium oxide series refractory material, and other premium properties of refractory material is improved.
Its solution is: at calcium oxide and contain and coat one deck at least on calcium oxide series refractory material (like the magnesia-calcium brick) substrate surface laser melting coating superficial layer is arranged, its cladding material is from the fusion of substrate surface self.Because laser melting coating can make the superficial layer of refractory material base material reach high densification and high-purity, apparent porosity greatly reduces, so can prevent calcium oxide fully and contain the aquation of calcium oxide series refractory material.And fire resistance, alkali resistance slag and the scum ability etc. of this refractory material are improved.
Above-mentioned calcium oxide and contain the calcium oxide series refractory material and comprise and burning till and unburned refractory material.
Laser melting and coating process has Fast Heating, condensation, hot input quantity is little, the heat affected area is little, and the coating dilution rate is low, coating thickness is controlled, coating and matrix are advantages such as adhere.Fast Heating, condensation reconfigure the cladding layer microstructure, and crystal grain obtains tangible refinement and even compact in the process of crystallization, and this is to waterproof of improving fire resistive material product, wear-resisting and corrosion resistance is very favourable; Hot input quantity is little, coating dilution rate low guaranteed original character of base material; Coating and matrix are adhere, have significantly improved the overall performance of fire resistive material product; Laser can carry out the constituency cladding, is particularly suitable for zonule and the surface modification needs that are difficult to access areas (like the internal face surface at the various metallurgical casting mouth of a river).With high performance surface and matrix adhere, obtain excellent more overall performance, obtain the performance higher with the less energy and material than matrix, have remarkable cost performance.Near-zero release, environmental pollution are littler, and process velocity is fast, machining accuracy is high, coating thickness is controlled, have the characteristics of high-quality and efficient significantly, energy-saving material-saving and environmental protection, are one of manufacturing technologies of advocating energetically of country.
Compare with traditional calcium oxide and the waterproof method that contains the calcium oxide series refractory material, this advantage that has the calcium oxide of laser melting coating superficial layer and contain the calcium oxide series refractory material is: processing is simple, sealing is reliable, long service life, be convenient to automatic assembly line production.For calcium oxide and to contain applying of calcium oxide series refractory material significant.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is the three-dimensional part sectioned view of one of the utility model embodiment.
Among Fig. 1,1. calcium oxide or contain calcium oxide series refractory material base material, 2. calcium oxide or contain the laser cladding layer of calcium oxide series refractory material base material self.
The specific embodiment
Among Fig. 1; At calcium oxide or contain on all surface of calcium oxide series refractory material base material (1); With laser melting coating one deck calcium oxide or contain the laser melting coating superficial layer (2) of calcium oxide series refractory material base material self; The microstructure of its superficial layer is reconfigured, and crystal grain obtains tangible refinement and even compact in the process of crystallization, reaches waterproof, wear-resisting and anti-corrosion purpose thereby make calcium oxide or contain the calcium oxide series refractory material.
