Abstract
A refractory material product with a laser-cladding surface layer is characterized in that one or multiple layers of clad layers manufactured through the laser cladding process are compounded on a working surface of a refractory material product base material, the material of the cladding surface layer is sourced by melting the surface cladding of the refractory material product base material, by melting additional modified materials or from the co-fusion of the surface of the refractory material product base material and the modified material.
Description
Technical field
A kind of fire resistive material product particularly has the fire resistive material product of cladding upper layer.
Background technology
The fire resistive material product surface; Especially workplace is the weak part that stands in the breach in its use, in abominable environment for use; Chemical erosion, physics wash away the rapid destruction of very easily causing the surface, thereby shorten the work-ing life of fire resistive material product greatly.The traditional method that improves at present fire resistive material product work-ing life mainly is whole purity, density and the firing temperature that improves its material.But be made in technology, equipment and cost aspect like this and exist many difficulties.If going up processing and manufacturing on the surface of fire resistive material product base material (especially workplace), the process method of our the enough various claddings of ability (especially laser melting coating) goes out the cladding layer of one deck modification; Will be easy to realize of Technology and the ideal product pursuit of refractory materials manufacturing field to " high-purity, highly dense and ultrahigh-temperature "; Thereby greatly improve fire resistive material product use properties and work-ing life, improve raw-material utilization ratio and reduce production costs, thereby can effectively reach the purpose of saving the resource and the energy.
Summary of the invention
For this reason, the invention provides a kind of fire resistive material product with laser melting coating upper layer.It is characterized in that: on the workplace of fire resistive material product base material, be compounded with one or more layers cladding layer with the laser melting and coating process processing and manufacturing; The material of its cladding upper layer can be from the fusion of fire resistive material product substrate surface self; Also can be from the material modified fusion that adds, or come from said two devices jointly and melt altogether.That is to say according to environment for use requirement, technology manufacturing requirement and cost performance requirement etc.; Working surface layers after the cladding of fire resistive material product base material can have three kinds of structure materials; The one, base material self material, the 2nd, base material with add the material modified material of melting altogether, the 3rd, the material modified material that adds fully.
Laser melting and coating process has rapid heating, condensation, hot input is little, the heat affected zone is little, and the coating thinning ratio is low, coating thickness is controlled, coating and matrix are advantages such as metallurgical binding.Rapid heating, condensation reconfigure the cladding layer microtexture, and crystal grain obtains tangible refinement and even compact in the crystalline process, and this is very favourable to the wear resistance and corrosion resistance that improves fire resistive material product; Hot input is little, coating thinning ratio low guaranteed original character of base material; Coating and matrix are metallurgical binding, 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-treated 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 metallurgical binding, 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, working 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.
Above-mentioned fire resistive material product base material comprises that mainly those starting material and technology cost are high, environment for use is abominable, work-ing life is short product is like the various metallurgical casting mouth of a river, various kiln tank block, Heat Room checker brick, air brick of steel ladle etc.These fire resistive material product base materials can be new products, also can be old system article that workplace has been etched, after using.
The workplace that is etched for various fire resistive material products carries out the cladding reparation and can greatly save the energy and resource.
The above-mentioned material modified AL of mainly containing that adds
2O
3, WC, TiC, SiC, ZrO
2Excellent in resistance is washed away Deng having, the material of anti-erosion, high temperature resistant, antioxidant characteristic.
For improving the density of cladding layer, the whole laser melting coating course of processing can be carried out under vacuum state.
