Advantages

Iron bars Features and Benefits

● uniform and dense microstructure

    Ordinary gray cast iron microstructure profiles for fine flake graphite (peripheral for small D-type graphite layer inside for small A-type graphite) and the matrix. Produce A-type (over 80%) and D (over 80%) graphite gray iron-based profiles.

    Nodular graphite tiny organization profiles rounded, high ball, the ball a few more, no intergranular carbide substrate is the best product in the production of ADI; compacted graphite iron profiles vermicular graphite number and shape requirements for consultation by both parties be.

● excellent mechanical properties

    Gray cast iron profiles: σb = 200 ~ 350Mpa, HB = 150 ~ 260; Mechanical properties of ductile iron profiles both high strength and high ductility, after conventional heat treatment to obtain various desired properties of the matrix structure Ha, σb = 375 ~ 900Mpa , HB = 150 ~ 300; after ductile iron machined components by isothermal quenching, σb = 800 ~ 1600Mpa, δ (elongation) corresponds to 22% to 1%.

● finished high

    Horizontal continuous casting and iron bars closed mold process produces good surface quality, the internal organization of dense, high dimensional accuracy, no sand, slag, porosity, shrinkage and other casting defects, also known as "dense stick", processing yield much higher than sand casting.

● excellent pressure resistance

    Good oil resistance properties, pressures up to 35Mpa, the thickness of ordinary conventional grades of iron bars for the processing of the sample 1mm no point infiltration and peripheral infiltration phenomenon, compressive strength greater than 1 to 2 sand casting, coupled with good processability performance, is the preferred substrate of high profile hydraulic parts.

● high fatigue limit strength

    High fatigue strength, fatigue limit is 40% higher than the sand casting.

● excellent surface coating

    Surface treatment is easy, cast profiles surface glass, enamel coating, copper, chromium, tungsten plating, carburizing, ammonia and other surface treatment, performance is much higher than sand castings and steel.

● rough saving, light weight, high precision, thermal deformation

    Sand casting blank material savings over 12% ~ 50%; the proportion of 8% lighter than steel and 10%, heat treatment, machining distortion is less than steel, more suitable for a variety of precision parts machining.

● machining performance

    Iron bars cutting resistance greater than sand casting, less steel, surface finish. Compared with sand casting, steel, cast iron profiles at different cutting speed, surface finish is relatively less volatile, not only at low speed (<50m / min), and at high speed (> 200m / min) during cutting, the surface roughness can ensure is not greater than 20μm: allowances and processing time are reduced by 50%; increase machining capacity from 10 to 50%; cutting is good, saving more than 50% sand castings; tool consumption by 70%, and steel and sand casting phase ratio, tool life 2 to 3 times.

● The total cost savings Parts

    Europe application proves: Use iron bars, down 50 percent from the use of sand casting and steel, parts of the total cost.
