Abstract

The utility model relates to an improved crystallizer, which belongs to the technical field of apparatus for treating covering metal materials. The crystallizer is composed of a funnel type hopper body, and a charging hopper, wherein, the funnel type hopper body is provided with a cooling box; the charging hopper is communicated with a pipe; a nozzle of the hopper body stretches out of the bottom surface of the cooling box along an axial direction with a same axial core, the length and the size of the nozzle are matched with the size of an inner cavity of a mold casting mouth of a continuous caster, and the mold casting mouth is connected with the cooling box. When the utility model is used, molten steel is ejected into the hopper body of the utility model, and meanwhile, alloy powders or compounds are put in the charging hopper which is communicated with the pipe of the hopper body, the alloy powders or the compounds are bonded and solidified with the surface layer of the molten steel, steel materials with large depth can be once formed, and the steel materials have the advantages that steel materials which resist corrosion prevent wear, the steel materials can bear high temperatures, energy can be saved, and alloy materials can be saved.

Description

Crystallizer

The utility model is a kind of improved crystallizer, belongs to the coating metal material and handles the device therefor technical field.

As everyone knows, many components of machine, structural member except having required higher mechanical properties, also require to have specific characteristics in one aspect energy.Such as the lining of crushing mechanism, except requiring higher impact toughness, the degree of depth wearing and tearing that also requirement can wear-resistant material; Such as the steel that are used for bridge, except having required good mechanical performance, also requiring can be anticorrosive; The cylinder cap of internal combustion engine also requires to have high temperature resistant property or the like for another example.In order to reach the purpose of wear-resistant grinding abrasion, prior art generally all is to adopt to add in steel casting that infusibility contains gold element or at its case-carbonizing, nitrogen; Or improve the hardness of iron and steel by heat treatment; Or in surface overlaying, compound etc.

In order to reach the erosion-resisting purpose in top layer, generally all adopt the method for in iron and steel, adding the corrosion-resisant alloy element at present.Concrete means are to take to spray, be coated with, plate or adopt combination process at steel material surface.This shows, except in ferrous materials, adding alloying element, reach the additive method that handle on the top layer, all belong to the iron and steel later subsequent treatment of becoming a useful person.And the additive method except combination process, all difficulty makes the processing degree of depth of ferrous materials can satisfy actual requirement.

The purpose of this utility model provides a kind of crystallizer that cast steel billet surface is handled that is mainly used in.But produce with using this crystallizer one-shot forming have the big degree of depth anticorrosive, resistance to wear, the ferrous materials on high temperature resistant top layer, and energy savings is saved alloy raw material.

The utility model is achieved in that

A kind of improved crystallizer, it includes the funneling bucket body of a band cooler bin.The end of bickering of this bucket body stretches out the cooler bin bottom surface and described cooler bin concentric is affixed from cabinets cavity.The height of bickering that stretches out the cooler bin bottom surface is complementary with general mold gate depth and inner chamber size thereof, improvements are that it also includes one and adds hopper, and this adds hopper and is funnel-form and has radially bicker with it a conveying pipeline that pipe connects and radially led to bucket body upper end headwall pipe by this conveying pipeline and connect.As above-mentioned because this improved crystallizer arranged, the technology of adding alloy powder no longer is simple spray, be coated with, plating, but can pass through this equipment, one have drop into alloy powder with common bucket body pipe logical add hopper so can pressurization on bucket, regulate the top layer alloying depth of steel such as cast steel base, just make the cast steel base have the surface alloy layered material of deep layer, and one-shot forming, obtain lasting anticorrosive, resistance to wear, resistance to elevated temperatures, make that simultaneously the inner alloy content of the cast steel base of production is unnecessary a large amount of minimizing of alloy material distribution thus, so both can reach the purpose of saving alloy material, help improving other mechanical performances of steel again, also saved the smelting energy simultaneously.

Below in conjunction with accompanying drawing the specific embodiment of the present invention is further described.

Accompanying drawing is the mold structure schematic diagram, wherein:

The 1-cooler bin 2-bucket body 21-3-that bickers adds hopper

The 31-conveying pipeline

With reference to accompanying drawing, the crystallizer of this embodiment is by a cylindrical cooling case (1) that can load cooling water, funneling bucket body (2) and the funneling hopper (3) that adds are formed, wherein bicker (21) axial concentric of bucket body (2) passes cooler bin (1) bottom surface and affixed with it, add hopper (3) and be positioned at cooler bin (1) top bucket body (2) one sides, the conveying pipeline (31) that adds hopper (3) is logical affixed by the bicker top headwall radial tubes that extends radially out with above-mentioned bucket body (2) of lower end.

The crystallizer that constitutes drops into when steel billet is produced and is stacked on the conticaster mold thus, and its bicker (21) are inserted to use in the mold cast gate and are proved to be respond well.Can add alloy powder or compound to adding hopper (3) easily in the time of towards bucket body (2) pour steel, while execute powder try out device for exerting in quarrel alloy powder in bucket exert pressure continuously so that bucket body (2) in thick shape molten steel top layer with also solidify gradually to prepare against and cut from adding the above-mentioned alloy powder bonding of hopper (3) through conveying pipeline (31) is transported to bucket body (2) in, reach designing requirement fully.

Claims

1, a kind of crystallizer, it includes the funneling bucket body of a band cooler bin.The end of bickering of this bucket body stretches out the cooler bin bottom surface and described cooler bin concentric is affixed from cabinets cavity; Stretch out cooler bin, the height of bickering of bottom surface is complementary with general mold gate depth and inner chamber size thereof, it is characterized in that it also includes one and adds hopper, this adds hopper and is funnel-form and has radially bicker with it a conveying pipeline that pipe connects and radially led to bucket body upper end headwall pipe by this conveying pipeline and connect.
