Stopper Rod System - Progelta
The Nozzle Cleaning System consists of a specially manufactured cylinder that plunges a steel bar through the nozzle hole to remove the slag build-up that causes narrowing of the diameter and consequently slows the liquid metal flow rate. The cleaning bar or pipe is a consumable part.
Steel Slag - an overview ScienceDirect Topics
Depending on the used production technology the steel slag can be divided into a basic oxygen steel slag an electric arc furnace slag and a ladle furnace slag De Brito and Saika 2013 . The steel slag is used as a secondary cementitious binder or aggregates for road construction Sheen et al. 2013 ; Manso et al. 2004 .

Ladles: Slag from the melting methods detailed above if not totally removed at the melting furnace will be transferred to the metal pouring ladles along with new slag generated during the metal transfer process. Because the walls of the pouring ladle are much thinner with little insulation more heat loss

How To Reduce Dross and Slag During Plasma Cutting
The term “dross” is often used interchangeably with the words “slag” and “spatter.” Whichever you choose to call it excessive buildup of hardened metal on your cut can lead to costly downtime needed for post-cut cleanup. While dross and slag are inevitable in the CNC plasma cutting process there are several ways to reduce them.

Method for improving operational efficiency in clogged
Typically inductor life may be as long as 18 months. However if slag build up occurs the useful life may be reduced to only a few months or in some extreme cases a few weeks. It is very difficult to remove accumulations of slag from the inductor loop or throat area.

Steel Hasle Refractories
Ladle top ring. The ladle top is most often damaged by chemical erosion because the ladle top ring is directly in contract with molten slag. This is sometimes what decides ladle service life. Thermal issues. If the ladle cools down during service stop thermal shock can lead to tension build-up and subsequent crack formation.

Silicon Carbide Crucible Silicon Carbide Graphite Crucible
With this information you can set up a program of routine crucible replacement that will minimize downtime. Control dross build up by cleaning regularly. Dross or slag build up is bad in every way as it can affect future metals that will be melted in the silicon carbide graphite crucible.
An Introduction To Tundishes African Pegmatite
Some of the impacts of slag have been previously touched upon and refractory-slag interactions are regarded as one of the most detrimental parts of casting 23 . Reports suggest that the optimal way of ensuring no build up of tundish slag slag from smelting and from the ladle should be removed ahead of reaching the tundish by physical or
Mortimer Smelter: Operations Description
basis to monitor and control slag matte and solid build-up. Slag is tapped almost on a continuous basis apart from occasions where repairs to spouts are required or when liquid levels are low. Slag is channeled from the spout into a stream of water to granulate it before being dewatered using a rake classifier.
Back to Basics with Ductile Iron Treatment ladles - Acetarc
The locking pins are lo ed in the ladle lifting bail and you don’t really want to be climbing up a ladder to remove the locking pins when the ladle is in operation. Conversely with small ladles there can be a stability problem as the ladle has a lot of weight high up when the sliding tun-dish cover is locked in the up position.
Manufacturing Process of Steel - Properties Fabri ion Uses
Converter carryover slag and synthetic slag additions are two elements of the ladle steelmaking system that can be considered together as they are the principal components which go to make up the ‘Ladle Top Slag’. The ladle top slag floats on the surface of the steel in the ladle and has a profound impact on the inclusion population in the

A carbide grade with additives to provide a resistance to build up? C-5C-6C-7 How good is the surface finish on the top side so that things won& 39;t stick? A rake change on the top surface to provide more sliding in the cut to remove any buildup? That leftover on the surface by the laser is simply rock hard but it also makes the mark more

Deflashing is the process of removing excess adhesive resin build up or molding compound. Deflashing can be accomplished through processes including media blasting wet blasting vibratory finishing tumbling and high energy systems.
Spinel Removal from PGM Smelting Furnaces
remove build up. The result however is that iron in the slag becomes reduced to the metallic form and alters the matte to a ‘malloy’ composition sulphur deficient . This superheated ‘malloy’ has the potential to dissolve copper coolers where installed and cause severe erosion of the coolers above the matte cooling blocks.
Treating ladle for ductile iron treatment - Sperry Corporation
Because of the depth of the treating ladle required to hold approximately 1400 pounds of molten base iron it is difficult to reach the bottom of the pocket to remove any slag build-up therefrom. In addition the greatest amount of lining erosion occurs around the pocket curve resulting in the need to patch this region on a regular basis.
