Abstract
A method for smelting with a titanium sponge protection container is characterized in that 1), a layer of titanium sponge batching is paved on the inner surface of the container before smelting, so as to save as an isolating layer, wherein the layer of titanium sponge batching is 100 to 300 mm in thickness and is paved loosely; 2), the container is cooled with circulating water, and is not in direct contact with liquid metal; 3), the upper surface of the isolating layer is in contact with molten metal, the lower surface of the isolating layer is in contact with the container, the middle of the isolating layer is a semi-melted layer, and high-density inclusions in the liquid metal are accommodated in the clearance of the isolating layer; and 4), metal of the same mark is smelted again without replacing the isolating layer. The method has the benefit that the liquid metal and the container can be separated, so that the liquid metal can be prevented from being polluted by other materials, and the purity degree of thee liquid metal is ensured.
Description
Technical field
The invention belongs to titanium ingot casting method technical field in nonferrous metallurgy engineering.
Technical background
In metal smelt process, need to use high temperature fluent metal container containing.High temperature fluent metal needs insulation, and container needs heat radiation, and this just relates to vessel insulation and heat radiation.Under normal circumstances, adopt refractory material to isolate high temperature fluent metal and low-temperature (low temperature) vessel, adopt recirculated water cooling container.This method can separation of liquid metal and container containing, but other materials can be made to pollute liquid metal.
Summary of the invention
Object of the present invention provides one can separation of liquid metal and container containing just in order to overcome defect that above-mentioned prior art exists, thus avoids using other materials to pollute the pure titanium or titanium alloy smelting process of liquid metal.
The object of the invention is to realize by following technical solution.
Utilize titanium sponge to protect container to carry out the method for melting, feature of the present invention is, 1), smelt before at inner surface of container, to spread a layer thickness be that the titanium sponge of 100mm ~ 300mm and metal target same recipe prepares burden is separation layer, this batching adopts loose laying;
2), container adopts circulating water, not direct and liquid metal contacts;
3), separation layer upper surface contacting molten metal, lower surface contacting container, centre is half melt layer, and gap holds the high density inclusions in liquid metal;
4), again smelt same trade mark metal, need not separation layer be changed.
The invention has the beneficial effects as follows, can separation of liquid metal and container containing, thus avoid using other materials to pollute liquid metal, guarantee the degree of purity of liquid metal.
Accompanying drawing explanation
Fig. 1 is process schematic representation of the present invention.
specific implementation method
See Fig. 1, a kind of titanium sponge that utilizes protects container to carry out the method for melting, feature of the present invention is, 1), smelt before at inner surface of container, to spread a layer thickness be that the titanium sponge of 100mm ~ 300mm and metal target same recipe prepares burden is separation layer, this batching adopts loose laying;
2), container adopts circulating water, not direct and liquid metal contacts;
3), separation layer upper surface contacting molten metal, lower surface contacting container, centre is half melt layer, and the high density that gap holds in liquid metal is mingled with;
4), again smelt same trade mark metal, need not separation layer be changed.
The present invention, when smelting titanium or titanium alloy, uses the titanium sponge raw material of formula of the same race as isolated material, separation of liquid metal and container containing, thus avoids using other materials to pollute liquid metal.
Embodiment one:
Metallurgy industry pure titanium TA1, adopt TA1 separation layer, thickness is 100mm.
