Description
Technical field:
A kind of instrument and working method that is used for the metal fever deformation technique relates to a kind of instrument, in particular for the instrument of metal fever deformation technique, and its working method.
Background technology:
In the thermal distortion of steel matter, the instrument of use need bear machinery, heating power and the wearing and tearing load of height, and instrument must stand the excellent quality that load could guarantee texturising prod, also will consider cheap instrument cost simultaneously.When hot seamless tube, the load condition of its instrument is near critical, and the instrument of steel duct contacts with the steel pipe inwall, therefore can't be cooled off fully and lubricate.For example, a perforating head is when wearing hollow billet, and pipe time of break-through can reach 20 seconds, and the load of 1200 celsius temperatures must be born in the top; Constantly heat absorption of top during this period, and possibly cause its Material Strength to descend thus, the top can't be born the pressure of deformable member material more afterwards; And then deformed damaged, perforation procedure is broken down, the top after the deformed damaged can not continue to use again; Must take out from the steel pipe the inside immediately, delay production like this, scrap instrument.The highest work-ing life of perforating head direct instrument cost and the production cost of influencing, fine top can reduce cost and guarantee to have the market competitiveness by tube quality.
At present, the HRS top generally adopts Thermal tool steel to make, and the material surface of top produces oxidizing reaction and generates a kind of red stone cortex; Several mm thick are arranged; Because the heat conductivility of red stone is very low, can play adiabatic effectiveness, so can protect the top material not receive the influence of high temperature and distortion.Still there is the very high life-span this top when wearing general carbon steel, and whenever only putting on hundred even thousands of hollow billets, but this HRS top can't reach the ideal effect when rolling high quality steel material.For example only can get to one or two pipe wearing the life-span that comes directly towards when chrome content is 13% steel alloy pipe.
Cause the of short duration reason of head lifetime to be since the hard integral part (for example chromium carbide) of material for the wearing and tearing on surface, top.In order to improve the head lifetime when the rolling high quality steel, following two kinds of schemes were once arranged, the top of promptly adopting high-hardness ceramic; Or on the steel top, adding the high firmness ceramic coating, the wearing and tearing of chromium carbide to the top can be resisted in this hard surface, but top coat comes off in deformation process easily; Top coat can thin down; Finally can not satisfy the adiabatic requirement, and top itself very fragility and easy fracture, its ceramic body is also extremely responsive for pulling force stress; Pulling force stress makes in the ceramic body and cracks, and crackle is expanded rapidly to extend and caused coming directly towards eventual failure.
The special ceramics material that employing has relative higher toughness and resistance still can't address the above problem.Up to now, all can't formally come into operation in Rolling Production in the top of ceramic material, can not guarantee to produce because the risk of top fracture is too big and carry out smoothly.
Summary of the invention:
The problem that the present invention will solve is exactly to provide a kind of to have adiabatic and antiwear instrument that is used for the metal fever distortion to above deficiency, and its working method.Its technical scheme is following:
The present invention is used for the instrument of metal fever deformation technique; Be with top coat on matrix; Its gordian technique is support lattice of on matrix, having the concave-convex type structure, on the support lattice, is coated with top coat, and top coat is made up of the pore between coating particles and the coating particles.
Be used for the working method of the instrument of metal fever deformation technique, may further comprise the steps:
1. the support lattice that on matrix, adhere to the concave-convex type structure;
2. supporting coated ceramic particle formation top coat on the lattice, form the pore between coating particles and the coating particles at top coat.
Compared with prior art the present invention has following beneficial effect:
1, the support lattice that on workpiece substrate, adhere to concave-convex type; Support on the lattice attaching surface coating again, can find out that by Fig. 1 top coat embeds the support lattice of concave-convex type, support lattice top coat is played the clamp effect; Top coat tightly is attached on the matrix thus; Support lattice and stoped coming off of when shear-stress produces matrix surface coating, can prevent that so thick top coat from being scraped, the raising insulation efficiency; Can prevent because the wearing and tearing that bring of chromium carbide, make perforating head when excessive high temperature, obtain the protection of long-time persistence.According to statistics, when wearing the steel grade of high chromium content, the present invention can wear 100 passages in every top; And 1 passage can only be worn in prior art red stone top; The present invention has come directly towards the instrument cost savings 99%, and the time of changing the top also shortened 99%, improved economy.
2, the pore of top coat can be strengthened the toughness of material, and its effect can make top coat be out of shape flexibly even have compressibility; The grain pattern of coating can make the crackle that produces once in a while no longer extend, and the crackle that at this moment produces can only reach next crystal boundary at most, because the tensile stress that crackle is produced through the particulate relative movement has disappeared.The porosity of pore can make instrument bear machinery, heating power and the wearing and tearing load of height and can not rupture easily in the top between 3%-40% like this, and the raising instrument is received the order, and guarantees to produce the excellent quality of carrying out and guarantees texturising prod smoothly, reduction instrument cost.
3, the present invention can stack top coat layer by layer on the support lattice, for example supporting elder generation's stacking one deck heat insulating coating on the lattice, on heat insulating coating, stacks the anti-wear coating of one deck then again, reaches the adiabatic and anti-wear effect of ideal.
