HORIZONTAL CONTINUOUS CASTING MACHINE

Horizontal Continuous Casting Machine HCCM–150.1.15.100 is used for production of continuously casted billets from liquid steel out of steel-smelting aggregates with volumes up to 15 ton. The machine is delivered with a set of equipment suitable to work in a single smelting mode.

SERVICE CONDITIONS

  • Enclosed space;
  • Surrounding temperatures from +5С up to +45С.
  • Relative humidity of air up to 80% at +35С.
  • Temperatures of cooling water from +5С up to +25С;
  • Surrounding environment must be explosive-free, and not contain aggressive gases or admixtures that are destructive for isolations and metals.
  • Cooling water should not contain any admixtures, which form sediment;
  • Temperature of cooling water cannot be lower than the temperature of the surrounding air by 15С (in order to avoid the formation of condensate).

HCCM -150.1.15.100 meets all safety measure requirements set by GOST 12.2.003-74 (RUS.) and 12.3.002-75 (RUS.).

TECHNICAL DESCRIPTION

The casting of liquid steel is done out of steel-casting ladle installed on a stand. The stand is equipped with metal-measuring equipment used during the process of casting. The working volumes of a metal reservoir are supplied with inert gas (Argon) with a pressure of 0.05…0.1 MPa at rates up to 0.1 m³/ton The casting areas are provided with emergency storages for holding excess metal during emergency situations and slag pot for slag tap. The metal is delivered to the metal reservoir with an open stream in a closed mantle, inside which Argon is delivered. The rate of Argon is up to 0.1 m3/ton under the pressures of 0.05…0.1 MPa. The delivery of slag-forming heat-insulating mixtures on the surface of the metal is done mechanically. The dimensions of grains are 0.5…1.5 mm. The amount of slag-forming mixtures delivered to the surface of the metal is 0.5…0.7 kg/ton.

During the process of casting, the billet is pulled from the mould by a withdrawal-roll set in a ‘pull-pause’ mode. The mould can be installed with an electromagnetic stirring system (ESS) with rotational motion of a liquid phase around the axis of the billet. The turning frequency of an electromagnetic field of the ESS is between 5 to 12 Hz, with the speeds of melt-stream movement of 0.6…1.2 m/sec.

The estimated flow of water for cooling of the mould is 3…3.3 m3/ton with pressure of 0.6 MPa. Additionally all other mechanisms and constructions that heat up are cooled. After the mould, at lengths of 2,50…3,00 m the air-water cooling of the billet is installed. It is recommended to use a secondary air-water cooling with water flow of 0.1…0.4 m³/ton and ratios of m³ of water and air in the ranges 1:10…50. The maximum ratio is set after the mould, minimum – at the end of the secondary cooling area. The stated above rates of water and air usage provide changes in temperature of the surface of the billet from 1150…1180 С after the mould, up to 950…1000 С on the withdrawal-roll set. The rate of use of water and air is regulated manually and automatically, depending on the speed of casting and the type of steel is possible to install a set of equipment used for electromagnetic stirring of the liquid phase of continuous ingot at the secondary cooling zone. The 200 ton hydraulic shear are installed after the withdrawal-roll set, which cut the continuous billets in measured lengths during the process of casting.  Billets are transported to the cooling bed by rollers conveyer, and depending on the working mode of the continuous caster they are then moved to the cooler, or the roller conveyer of the commuting heating furnace.
