Abstract
A continuous coating line includes a snout assembly exposed to molten metal. The snout assembly includes a snout tip positioned about a steel strip that is immersible in the molten metal to provide a seal around the steel strip during entry into the molten metal. The snout tip includes a refractory material that is resistant to wear, abrasion, and corrosion when the snout tip is exposed to the molten metal.
Claims16
A snout tip for use in a snout assembly of a continuous coating line, wherein the snout tip comprises:
- a bottom portion comprising a body defining an opening therethrough for receiving a steel strip, wherein at least a portion of the body is configured to be immersed in molten metal, wherein the body comprises a refractory material;
- and
- a support coupled with the bottom portion for supporting the bottom portion relative to the snout assembly, wherein a portion of the support extends within the body of the bottom portion, and wherein the support comprises a flange positioned above the body of the bottom portion.
A snout tip for use in a snout assembly of a continuous coating line, wherein the snout tip comprises:
- a bottom portion comprising a body defining an opening therethrough for receiving a steel strip, wherein at least a portion of the body is configured to be immersed in molten metal, wherein the body comprises a refractory material;
- a support coupled with the bottom portion for supporting the bottom portion relative to the snout assembly, wherein a portion of the support extends within the body of the bottom portion;
- and
- a seal positioned between the support and the bottom portion configured to maintain a pressure within the snout tip.
A coating portion of a continuous coating line configured to receive an elongated steel sheet for coating the steel sheet comprising:
- a hot dip tank for receiving molten metal;
- one or more roll assemblies for supporting the steel sheet through the coating portion;
- and
- a snout assembly positioned about the steel sheet at an entry of the hot dip tank, wherein the snout assembly comprises:
- a bottom portion comprising a body defining an opening therethrough for receiving a steel strip, wherein at least a portion of the body is configured to be immersed in molten metal, wherein the body comprises a refractory material;
- a support coupled with the bottom portion for supporting the bottom portion relative to the snout assembly, wherein a portion of the support extends within the body of the bottom portion;
- and
- a seal positioned between the support and the bottom portion configured to maintain a pressure within the snout tip.
