Description
Technical field
The present invention relates to a kind of manufacturing approach of hot continuous rolling unit manufacture order face stainless steel clad plate, belong to technical field of steel rolling.
Background technology
At present, the suitability for industrialized production stainless steel clad plate mainly contains two kinds of methods, blast composite algorithm and direct hot rolling composite algorithm.Wherein explosion method is to utilize the percussion of the detonation wave of explosive charge generation, makes by compound metal and parent metal and produces bump each other, thereby realize the welding of two kinds of metals; This method generally can only be produced multiple layer thickness in the thick single-side stainless steel composite plate of 2～16mm; Because of layer is thicker again; This method can only be used to produce the stainless steel clad plate of thicker specification, and is simultaneously serious because of the blast process environmental pollution, makes this method be difficult for being used more widely.Directly rolling is that stainless steel and substrate with surface cleaning fits together each other, and the edge welding is obturaged, and realization stainless steel and substrate is compound under uniform temperature and draught pressure; This method complex process, interface bond strength is lower, causes the product shearing strength low, and the control of product quality difficulty is big, and production cost is high.Two-sided stainless steel clad plate is the stainless steel double layer because of upper and lower surfaces, and its rolling mill practice is simple relatively, ripe.And adopt the hot rolling method to produce single face stainless steel clad plate technology; Because of basic unit is made up of two kinds of resistances of deformation and different stainless steel and the substrates (straight carbon steel or low-alloy steel) of thermal coefficient of expansion with multiple layer; Produce serious " nose " or " discount " phenomenons because of two kinds of materials distortion inequalities during normal hot rolling; Influence normally nipping of milling train, cause the operation of rolling to be compelled to stop, hot rolling production difficulty is very big.For the production of single-side stainless steel composite plate, the Chinese patent publication number is the patent documentation of CN 101015835, relates to a kind of production method of stainless compound steel plate; Described single-side stainless steel/carbon steel or low alloy steel composite plate is produced, and its main technical schemes is to produce the single-side stainless steel composite plate blanks with explosion method, and the surface roughness of the single-side stainless steel of above-mentioned slab being answered layer is polished to Ra≤25; Stainless steel double layer to polishing sprays one deck interleaving agent equably; After drying in the shade the two boards base is stacked, and welding, heat subsequently and hot rolling; The slab that will pass through hot rolling is at last cut the limit, separates into two stainless steel compound plates; Producing single face stainless steel clad plate because of this manufacturing approach need carry out the polishing of stainless steel double laminar surface, spraying interleaving agent, two boards base and cut limit and separation after stacking and weld, having rolled; Therefore this method production process flow process is complicated, and production cost is high, production efficiency is low.
In order to satisfy the demand of industries such as increasing civilian, building, oil, chemical industry, storing, water conservancy and hydropower to the single-side stainless steel composite plate; Demonstrate fully the single face composite plate exclusive low-cost advantage, on the hot continuous rolling unit, developed single-side stainless steel composite plate manufacturing process, other production technologies of comparing; This technology can make full use of existing rolling equipment; The compound roll bending of producing of stainless steel has clear superiority in plate shape and surface quality control, can realize continuous, the production in enormous quantities of single-side stainless steel composite plate simultaneously, product each item function admirable; Satisfy standard-required fully, the part index number surplus is bigger.
