Abstract
The invention provides a producing method for a double-fluid bimetal complex casting hammer type hammerhead. Two casting systems are used. Firstly, low-alloy steel or common cast steel are cast at the cast steel gate, when the molten steel reaches the complex boundary or is a little lower than that, according to the size of the cast, after spacing 3-120 seconds, high-chromium cast iron or high alloy steel are cast into the high-chromium cast iron gate, and chill material is placed at the cast steel part of the steel and iron connection position, to ensure the crystal boundary surface and the base body to have a certain temperature gradient, a certain thickness and a intact boundary surface. Since the hammerhead is made of high-chromium cast iron, the hammer handle is made of low-alloy steel or common cast steel, wearing resistance property of high-chromium cast iron and strong toughness of hammer handle steel are both utilized, so that the use characteristic of the hammerhead is optimized.
Description
Affiliated technical field
The present invention relates to a kind of production technique method of double-liquid bimetal composite casting hammer type hammerhead.Especially place chill material by faying face place, have the manufacturing technique method of a kind of double-liquid bimetal composite casting hammer type hammerhead of certain thermograde to guarantee crystalizing interface and matrix two kinds of materials.
Background technology:
Hammer type hammerhead is the strength member on the disintegrating machine, also is to consume maximum, the part of easy damage on the disintegrating machine.At present, traditional hammer type hammerhead of the various models that domestic disintegrating machine uses all is to adopt medium carbon alloy steel, potassium steel or rich chromium cast iron mostly.Though medium carbon alloy steel and potassium steel toughness are good, hardness is low, and wear resistence is relatively poor relatively, and tup is low service life; Though the rich chromium cast iron wear resistence is good, relatively poor because of its toughness, easy shank at tup ruptures in the use.
The manufacturing technique method of double-liquid bimetal composite casting hammer type hammerhead, because tup has adopted rich chromium cast iron, hammer handle adopts low-alloy steel or normal steel casting material to make, promptly brought into play the good effect of the wear-resistant part rich chromium cast iron of tup wearability, also brought into play the strong speciality of hammer handle steel material toughness, obviously increased the service life of tup.
Summary of the invention:
In order to overcome the relatively poor relatively and in use easy deficiencies such as shank generation fracture of rich chromium cast iron of existing hammer type hammerhead material wearability, the invention provides a kind of manufacturing technique method of double-liquid bimetal composite casting hammer type hammerhead at tup.
Technical scheme of the present invention is: adopt two running gate systems, pour into cast steel earlier, when molten steel reaches the compound interface of technological requirement or when some slightly down, according to the foundry goods size, 3-120 second at interval, afterwards, pour into rich chromium cast iron again, and, have certain thermograde and certain thickness and complete combination interface to guarantee crystalizing interface and matrix at the cast steel place of iron and steel connecting portion placement chill material.
The invention has the beneficial effects as follows, owing to adopt the double-fluid double metal composite casting method to produce hammer type hammerhead, make working face have very high wearability, hammer handle partly has good impact flexibility, given full play to the speciality of various materials, the serviceability of tup is optimized.
Description of drawings
Be in conjunction with the accompanying drawings the present invention to be done detailed explanation below.
Accompanying drawing 1 is the casting technique schematic diagram of biliquid bimetallic composite casting hammer type hammerhead. 1 is watering, emitting of rich chromium cast iron among the figure Mouthful, be used for casting or feeding rich chromium cast iron or high-alloy steel liquid; 2 is watering, emitting of casting low-alloy steel or normal steel casting among the figure Mouthful, its position is used for pouring into a mould and the feeding molten steel below the height of the liquid position of required molten steel; 3 is chill materials among the figure, Be used for accelerating the molten steel cooling, prevent the batch mixing phenomenon, be placed on below the biliquid faying face, according to the foundry goods size, can be placed on hammer Both sides that binding site is following or all around.
Accompanying drawing 2 is biliquid compound casting tup schematic diagrames among the present invention. Tup position material is rich chromium cast iron or high-alloy steel, Hammer handle position material is low-alloy steel or normal steel casting, has very high wearability to guarantee working face, and the hammer handle position has well The shock resistance effect.
The specific embodiment
Adopt two running gate systems, earlier pour into low-alloy steel or normal steel casting at cast steel cast gate place, when molten steel reaches compound interface or slightly down a bit, according to the foundry goods size, at interval 3-120 second, afterwards, pour into rich chromium cast iron or high-alloy steel at rich chromium cast iron cast gate place again, and, have certain thermograde and certain thickness and complete combination interface to guarantee crystalizing interface and matrix at the cast steel place of iron and steel connecting portion placement chill material.
Claims (5)
1. the manufacturing technique method of double-liquid bimetal composite casting hammer type hammerhead is characterized in that adopting two running gate systems, and places the manufacturing technique method of a kind of double-liquid bimetal composite casting hammer type hammerhead of chill material at the cast steel place of iron and steel connecting portion.
2. the manufacturing technique method of double-liquid bimetal composite casting hammer type hammerhead according to claim 1, it is characterized in that adopting the method for rich chromium cast iron and cast steel double-fluid double metal composite casting, and at the cast steel place of iron and steel connecting portion placement chill material, to guarantee that crystalizing interface and matrix have certain thermograde and certain thickness and complete combination interface.
3. the manufacturing technique method of double-liquid bimetal composite casting hammer type hammerhead according to claim 1, it is characterized in that adopting two running gate systems, pour into cast steel earlier, according to the foundry goods size, 3-120 pours into rich chromium cast iron again after second at interval, makes the bimetallic compound interface obtain good feeding.
4. the manufacturing technique method of double-liquid bimetal composite casting hammer type hammerhead according to claim 1 is characterized in that the difference according to the part time job environment, and working face can adopt rich chromium cast iron or high-alloy steel material.
5. the manufacturing technique method of double-liquid bimetal composite casting hammer type hammerhead according to claim 1, what it is characterized in that hammer handle partly adopts is low-alloy steel or normal steel casting material.
