Abstract
The utility model discloses a kind of double cooling roll assemblies of nanocrystalline pocket builder, including holder, chill roll one and chill roll two, chill roll one is fixed on by bearing one on holder, chill roll two is fixed on by bearing two on holder, and positioned at the underface of chill roll one, it is inner cooling path among the chill roll one and chill roll two, the inner wall of the inner cooling path is equipped with spiral groove, condenser pipe one is embedded in one spiral groove of the chill roll, the inlet end and an outlet end of the condenser pipe one is located at one right end of chill roll, condenser pipe two is embedded in two spiral groove of the chill roll, the inlet end and an outlet end of the condenser pipe two is located at two left end of chill roll, two kinds of the condenser pipe one and condenser pipe are equipped with circularly cooling agent.By the interaction of two chill rolls, solve the problems, such as that single chill roll temperature difference between the two ends are excessive.
Description
Technical field
The utility model is related to chill roll technical field, double cooling roll assemblies of specifically a kind of nanocrystalline pocket builder.
Background technology
The soft state alloy strip steel rolled stock of amorphous is produced by quick emergency cooling process by single roller pocket builder, in system band process
In, high temperature master alloy melt is ejected into high-speed rotating chill roll by nozzle and puts on, and chill roll covers high speed rotation and inside
By cooling water cooling, molten metal liquid is quickly cooled down in cooling roller surface and is thrown out of and strip is made.Currently, traditional
Chill roll designs interlayer, incorporates cooling water in interlayer, and condensed water is directly contacted with the inner wall of roll body, and roll body is caused to expand with heat and contract with cold,
It is easy cracking, while can also cause the corrosion of roll body, is reduced the service life.Since the processing of the soft state alloy strip steel rolled stock of amorphous is to water cooling
It is required that relatively high, in simple terms, entire technological process be molten steel when 1400 degree by atwirl cooling roller, wink
Between be cooled to room temperature, to form disorderly arranged molecular structure, therefore referred to as non-crystalline material.Cooling cannot reach expection and most close
Key is the crystallization effect that can influence material itself, to influence the magnetic property of subsequent product, and can increase the brittleness of material,
Both so that processing efficiency reduce more so that artificial waste, the increase of cost.
Utility model content
Purpose of utility model：Existing problem and shortage in for the above-mentioned prior art, the purpose of this utility model are
A kind of double cooling roll assemblies of nanocrystalline pocket builder are provided.
Technical solution：In order to achieve the above objectives, the utility model a kind of nanocrystalline pocket builder double cooling roll assemblies,
Including holder, chill roll one and chill roll two, chill roll one is fixed on by bearing one on holder, and chill roll two passes through bearing two
And be fixed on holder, and be inner cooling path, institute among the underface of chill roll one, the chill roll one and chill roll two
The inner wall for stating inner cooling path is equipped with spiral groove, and condenser pipe one, the condenser pipe are embedded in one spiral groove of the chill roll
One inlet end and an outlet end is located at one right end of chill roll, and condenser pipe two is embedded in two spiral groove of the chill roll, described cold
The inlet end and an outlet end of solidifying pipe two is located at two left end of chill roll, and two kinds of the condenser pipe one and condenser pipe are equipped with circularly cooling
Agent.
Further, the circulating coolant is cooling water, cooling water temperature≤15 DEG C.
Further, the inner wall of the inner cooling path is equipped with cold-hot alloy-layer and corrosion resisting alloy layer, the corrosion resistant
Erosion alloy-layer is arranged on the surface of cold-hot alloy-layer.
Further, the cold-hot alloy-layer is nickel-molybdenum alloy layer, and the corrosion resisting alloy layer is chrome-nickel layer.
Further, the surface of the chill roll one and chill roll two is uniformly provided with ceramic wearing coat.
Above-mentioned technical proposal can be seen that the beneficial effects of the utility model：
A kind of double cooling roll assemblies of nanocrystalline pocket builder described in the utility model, reasonable in design, chill roll
One and chill roll two water inlet end respectively both ends design, by the interaction of two chill rolls, solve single chill roll two
The problem of holding excessive temperature differentials is equipped with condenser pipe in the inner cooling path of chill roll one and chill roll two, can effectively avoid cooling water
It is in direct contact with chill roll, while realizing cooling effect, chill roll can be avoided to expand with heat and contract with cold cracking phenomenon, prolonged
The service life of long chill roll.
