Description
The present invention is a kind of support equipment and the manufacturing process that is used on the metallurgical machinery sector sinter machine.
At present, there is not the ideal terms of settlement so far with discaling roll, grate plate and the manufacturing process of the matching used thermal crusher of sinter machine in the metallurgical machinery sector both at home and abroad.The thermal crusher discaling roll that manufactures and designs now adopts and is with several gear rings in the outside of six-edged axis, the outside of gear ring uses screw the crushing teeth of alloying steel Mn13, grate plate is contained in the crushing teeth bottom, accept agglomerate and under the continuous shear extrusion of crushing teeth, with the fragmentation of thermal sintering piece, bear heat and wear and tear bigger than crushing teeth, no water cooling plant, the discaling roll and the grate plate that contact at agglomerate with 700 ℃ of high temperature, annealing softening loses fastness to wear, only 3 months life-span, the workman changes discaling roll and grate plate labour intensity is big, waste man-hour and starting material seriously influenced mechanize work efficient, and the manufacturing process of thermal crusher discaling roll and grate plate are also relatively backward, can not satisfy the production needs, therefore develop a kind of discaling roll of thermal crusher, grate plate and manufacturing process are new problems anxious to be solved both at home and abroad always.
Purpose of the present invention to be exactly that a kind of structure design is simple in order providing, manufacturing process reasonable, to adopt inner water-cooled, operate outside position built-up welding heat-resistance abrasion-resistance alloy, improve the life-span of discaling roll and grate plate, enhance productivity, reduce cost, reduce thermal crusher discaling roll, grate plate and the manufacturing process of labor strength.
The object of the present invention is achieved like this: whole device is made up of discaling roll and grate plate, discaling roll comprises master wheel, key, bearing support, roller, tooth, sheath, master wheel is keyed on the roller, bearing support is contained in the roller two ends and is fixed on the basis, and the roller inner core has two paddle holes, and there are two paddle holes tooth inside, tooth is arranged on the roller equably, in the roller in paddle hole and the tooth paddle hole corresponding just, weld together then, sheath is contained in the roller two ends; Grate plate comprises grate plate parent, grillflooring, flange, two paddle holes are arranged in the grate plate parent, the two ends mounting flange, two grillfloorings of symmetric arrangement and welding together on each grate plate parent, flange is fixed on the basis, and the prescription of discaling roll and grate plate working position surfacing welding electrode is: high carbon ferro-chrome 28%, mid-carbon fe-mn 1.45%, molybdenum-iron 1.8%, vanadium iron 3%, graphite 3.5%, lead powder 1.5%, marble 0.7%, quartz 5.4%, titanium dioxide 5.4%, rhombohedral iron ore 1.15%, fluorite 1.75%, carbon west potassium 0.3%, organism 46.05%.Discaling roll and grate plate working position adopt the Chemical Composition of heat-resistant wear-resistant welding rod deposited metal to be: C 3.21%, SiO, 57%, Mn1%, Cr29.87%, Mo0.14%, P 0.031%, and S 0.019%, Al0.024%, B 0.0068%, and V 0.2%, Fe64.9292%.The bead-welding technology of discaling roll and grate plate adopts welding current 950-1000A, discaling roll and grate plate are divided into dice, by the heat transferred motherboard of lattice plate with the absorption of built-up welding surface, restrain the temperature rise of built-up welding part and reduce high temperature oxidation and wearing and tearing, during built-up welding, welding rod front end and motherboard are at a distance of 5-7mm, after the striking, watch the lattice plate attentively and welding deposit boundary molten metal rises along the lattice plate, electric arc is left from the lattice plate, use carbon-point immediately instead, heat at the built-up welding surface arcing, make the discharge of floating internally of the metal gas that remains in metal inside and nonmetal slag inclusion, built-up welding is polished with emery wheel.Main points of the present invention are its structural shape and manufacturing process.Its principle of work and working method are: thermal crusher is to use the shear extrusion principle agglomerate is broken into fritter in thermal environment.By the motor drives master wheel, discaling roll is rotated thereupon, agglomerate enters from chassis on the grate plate of thermal crusher, and discaling roll is broken into fritter with agglomerate under hot state, fall along the grate plate gap, is transported to blast furnace ironmaking by feed belt again.
Concrete structure of the present invention is provided by following examples and accompanying drawing thereof.
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the sectional view of Fig. 1.
With reference to accompanying drawing, whole device is made up of master wheel 1, key 2, bearing support 3, roller 4, tooth 5, sheath 6, grate plate parent 7, grillflooring 8, flange 9, master wheel 1 usefulness key 2 is fixed on the right-hand member of roller 4, bearing support 3 is contained in roller 4 two ends and is fixed on the basis, tooth 5 is evenly arranged on the roller 4 and together, sheath 6 is contained in roller 4 two ends, grate plate parent 7 two ends mounting flanges 9, two grillfloorings 8 of symmetric arrangement are fixed on flange 9 on the basis on each grate plate parent 7.
Hot cracker teeth roller and grate plate compared with prior art have reasonable in design, manufacturing process is simple, cost is low, the life-span is long, reduce labor strength, the advantage such as enhance productivity, and will be widely used in the metallurgical machinery sector.
