Abstract
The utility model belongs to blast furnace iron-making technical field, specifically relates to a distributing chute plate for blast furnace iron-making. The chute plate comprises a base plate and a high wear resistant alloy steel, wherein uniformly distributed dovetail grooves are transversely disposed on the base plate; the strip shaped high wear resistant alloy steel is embedded in the dovetail groove, the cross section of the high wear resistant alloy steel matches with the shape of the dovetail groove and is embedded into the dovetail groove, and the upper surface of the high wear resistant alloy steel is slightly higher than the surface layer of the base plate. The distributing chute plate has the advantages of concise structure, convenient embedding, long service life (more than 1.5 years), smooth material sliding, and fulfillment to production requirements.
Description
Technical field
The utility model belongs to technical field of blast furnace ironmaking, is specifically related to the distributor chute liner plate that a kind of blast furnace ironmaking is used.
Background technology
The form of the blast furnace material distribution chute liner plate of ironmaking usefulness is divided into two kinds substantially at present: flat liner plate and backing strap liner plate.Backing strap formula liner plate, as shown in Figure 1, expect its advantage: because of the backing strap effect is arranged, so work-ing life is longer, 〉=9 months.Shortcoming: because of there is material spring (lastics effect) in second drop point, so incompatible production.
Flat liner plate (built-up welding liner plate), as shown in Figure 2.Its liner plate bottom is provided with stiffening web.Its advantage is: the material that slips is unobstructed, can adapt to and satisfy the production demand.Shortcoming: second drop point is easy to wear, so work-ing life is short, and only 3～6 months,
Another kind of flat liner plate is double-deck flat liner plate (a built-up welding liner plate), is formed by the flat liner plate stack combinations of two-layer built-up welding, as shown in Figure 3.Its advantage is identical with the s-generation, and the material that slips is unobstructed, can adapt to and satisfy the production demand.Shortcoming: work-ing life is still shorter ,≤9 months.
Summary of the invention
The object of the present invention is to provide a kind of slide material unobstructed, satisfy the production demand, and the blast furnace material distribution chute liner plate of long service life.
The blast furnace material distribution chute liner plate that the utility model provides is constituted by substrate and highly wear-resisting alloy steel, and substrate can be made with general steel plate, also available abrasion-proof stainless steel cast molding.Substrate laterally is provided with equally distributed dovetail-indent, and highly wear-resisting alloy steel is a strip, the dovetail-indent shape coupling on its cross section and the substrate, and be embedded in the dovetail-indent of substrate, its upper surface plays the effect of guide's mill a little more than the substrate top layer.Structure is seen shown in Figure 4.The high-wear-resistant alloy steel can adopt HRC etc.
In the utility model, the substrate length and width determine that according to actual needs thickness is 35-50mm, and the width suitable for reading of dovetail-indent is 20-35mm, and the width of going to the bottom is 25-40mm, and the width of going to the bottom highly is 20-35mm greater than width suitable for reading.The width between centers of adjacent two dovetail-indents is 45-75mm.The height of strip highly wear-resisting alloy steel is greater than dovetail-indent height 2-6mm.
The advantage of this distributor chute liner plate:
1, highly wear-resisting alloy steel hardness height (for example HRC can reach more than 90) is equipped with wear-resisting substrate in combination, and can reach more than 1.5 years work-ing life.As increase the height dimension (the dovetail-indent height increases simultaneously) of wear-resisting alloy steel, and then corresponding increase in work-ing life, that is: the life-span is directly proportional with height dimension.
2, the slide material is unobstructed, satisfies the production demand,
3, do not use fixedly embedding technique of bolt class, do not use auxiliary member welding fixed class embedding technique yet, simple for structure, inlay conveniently.
Description of drawings
Fig. 1 is backing strap lining plate structure diagram.Wherein, (a), (b) be cross-section illustration for the plane diagram.
Fig. 2 is the flat lining structure diagram.Wherein, (a), (b) be cross-section illustration for the plane diagram.
Fig. 3 is double-deck flat lining structure diagram.Wherein, (a), (b) be cross-section illustration for the plane diagram.
Fig. 4 is a structural diagrams of the present utility model.Wherein, (a), (b) be cross-section illustration for the plane diagram.
Number in the figure: 1 is substrate, and 2 is dovetail-indent, and 3 is highly wear-resisting alloy steel (strip).
Embodiment
Adopt the wear resisting steel casting technique and be machined into processing dovetail-indent 2 on the substrate 1, also can utilize general steel plate as substrate 1, prepare dovetail-indent 2 with machining, adopt block-by-block after highly wear-resisting alloy steel or nonmetallic wear-resistant material (as the pottery etc.) machine-shaping to be embedded in the dovetail-indent of substrate and can realize.Usually, the length and width of substrate determines that according to actual needs for example: long 2500mm, width 1050mm, the thickness of substrate are 45mm.Dovetail-indent on it width suitable for reading is 26mm, and the width of going to the bottom is 30mm, highly is 25mm.Highly wear-resisting alloy steel is processed into strip, is bumped into piecemeal, and total length is consistent with substrate width, the dovetail-indent cross-sectional shape coupling on cross section and the substrate, and height is a little more than the dovetail-indent height.Promptly get the required blast furnace material distribution chute liner plate that satisfies the production demand, reach more than 1.5 years its work-ing life.
Claims (2)
1, a kind of blast furnace material distribution chute liner plate, it is characterized in that constituting by substrate and high-wear-resistant alloy, its plate laterally is provided with equally distributed dovetail-indent, high-wear-resistant alloy is a strip, the dovetail-indent shape coupling of its cross section and substrate, and be embedded in the dovetail-indent of substrate, its upper surface is a little more than the substrate top layer.
2, blast furnace material distribution chute liner plate according to claim 1, it is characterized in that said substrate thickness is 35-50mm, the width suitable for reading of dovetail-indent is 20-35mm, the width of going to the bottom is 25-40mm, go to the bottom width greater than width suitable for reading, highly be 20-35mm, the width between centers of adjacent two dovetail-indents is 45-75.
