FRALCO Fully Automatic Refining Car in front of Furnace
FRALCO Fully Automatic Refining Car in front of Furnace 1. Refining vehicles adopt tank crawler chassis or wheeled chassis, which can meet the needs of different ground conditions in the foundry. 2．The refining car in front of the furnace has two forms: rotor type and nozzle type, and the powder injection speed can reach 6kg/m. 3. The nozzle refining car can reciprocate horizontally in front of the furnace, longitudinally reciprocating refining in the furnace, and the dead zone on the furnace side elbow refining. Different furnace types have different running trajectories to ensure uniform refining and no dead zones. 4. The rotor refining car can realize multiple refining modes such as lateral movement refining in front of the furnace, fixed-point refining, and rotor swing refining. The thrust of the rotor is large enough to realize refining without dead zone. 5. There is a perfect thermal protection layer around the car body to prevent heat radiation from damaging the car body components. 6. The refining vehicle can use various refining media such as argon, argon-chlorine mixed gas, argon + refining agent, argon + carbon tetrachloride. 7. Fully automatic refining car in front of the furnace, which completely replaces labor, saves refining agent, reduces production cost, reduces labor intensity, employee satisfaction, boss satisfaction

MDB -Cartridge Lining The MDB-Cartridgeis a refractory furnace lining that is easily replaced. When the furnace refractory needs to be changed, the spent cartridge is lifted by using aspecially designed spreader bar and a crane. After the used MDB-Cartridge is removed, a new lining can be installed within a few hours. The one piecerefractory lining is manufactured by FRALCO division under controlled conditions in our pre-cast shapes manufacturing facility. The design using high temperature refractory and multiple layers of insulation provides maximum service life and superior insulation. The lining is pre-fired in our manufacturing facility to remove all moisture. After preheating on site, it is ready to use. Advantages Produced under optimal conditions. Easily replaceable pre-fired refractory lining. Reduced man power needed for the relining.Reduced preheat time. All moisture and chemically combined water has been removed during manufacture. Downtime of the MDB furnace reduced up to 90%. Graphite Products Graphite products include machined rotors, shafts, and screws.

FRALCO Deep Bed Filter
Aluminium alloys need to meet ever more stringent quality requirements, particularly for beverage cans, foils, fine wires,lithographic sheets and bright trims. In fact, inclusions lead to problems when metal is produced to ever decreasing thicknesses approaching those of the inclusion size or when surface quality is paramount. The FRALCO Deep Bed Filter consists of an insulated box containing layers of carefully sized alumina balls through which molten aluminium flows from top to bottom. The filtering area, or bed, is sized as a function of metal flow rates Advantages 5μm Inclusion removal efficiency higher than 95%, LiMCA and PoDFA analyses show best quality requirements consistently achieved with DBF; Different ball sizes and variable layers allow custom quality requirements. Excellent constancy and repeatability of results; Productivity Environment.Preheat station permits quick change of filter box to avoid downtime.

FRALCO Alumina Ball Cleaning Machine
FRALCO Alumina Ball Cleaning Machine Generally, the heat exchange ball is used for about 3 months, and the top part of heat exchange ball of the heat exchange box will be partially damaged because of the influence of long-term rapid cooling and heating. And because the furnace gas itself is not clean, it will cause dust pollution to the heat storage ball inside the heat storage box. Heat storage ball needs to be cleaned, replaced and replenished regularly. In order to improve the life of the regenerative ball and reduce the labor intensity of the workers, the company has developed a regenerative ball washing machine, which can effectively improve the service life of the regenerative ball and reduce the cost. ALMELT Heat Storage Ball Characteristics the alfa alumina (corundum) spheres were made by sintering the spheroidized calcined alumina at a melting point temperature of 3704℉(2040℃. The main process is divided into rolling and pressing. In the working process, many heat storage balls in the heat storage tank divide the air flow into very small flow strands, and the air flow forms strong thunderstorm when it flows in the heat conduction body, which can effectively absorb the heat on the surface of the heat conduction body, so the regenerative burner can be changed frequently and quickly. After the high temperature gas flows through the regenerator, the temperature can rise to only about 100℃ lower than the flue gas temperature, and the temperature efficiency is more than 90%. The corundum heat storage ball is made of industrial alumina as the main raw material. It has the characteristics of low shrinkage, high temperature load softening temperature, corrosion resistance, high strength, large heat storage and discharge, good thermal shock stability, good thermal conductivity and small number of thermal expansion.depending on customer requirements, the diameter of the ball varies from 1/8 inch to 2 inch (tolerance ±6% mm).
