Waterproof enclosures with protection grades IP67 or IP68 for outdoor use are not automatically sealed against vapour and humid air. To avoid negative pressure, high humidity and condensation inside the enclosure a continuous Ventilation and pressure equilibrium is necessary. This function can be achieved by using a venting element made by Jacob. Features: - Continuous ventilation and adaptaion on the inner pressure - Hydrophobic and oleophobic PES- membrane - Body from stainless steel 1.4305 - Theoretical air flow through usable surface up to 75 l/h at Delta-p = 0,07 bar - Water entry pressure >= 0,83 bar (dynamic WEP, 30 seconds) - Temperature range -40°C / +100°C - Protection grade IP66 / IP68 - 0,6 bar (60 min.) / IP69

The WADI heat cable gland made of stainless steel 1.4404 / AISI 316L is the perfect cable entry solution for high temperature applications up to +200°C. It has also a very good resistance against many chemicals. Features: - large-area sealing protects the cable - integrated anchorage with high retention - wide sealing and clamping range - for cables from 3 to 53 mm - the inner sealing ring can be removed easily for larger cables - high UV, ozone and weather resistancy - temperature range -40 °C / +200 °C (dynamic) - protection grade IP 66 / IP67 / IP69 - very good resistance against many chemicals - with metric thread from M12 to M63

Alloy Cast Steel Roll materials are eutectoid steel and hypereutectoid steel. Adding alloy content such as Cr, Ni, Mo, and V up to more than 0.8%, carbon content 0.4~1.3%. The matrix structure, after heat treatment of normalizing and tempering, becomes sorbite and tempered sorbite. This type of steel mill roll possesses high strength, good toughness, good resistance to hot cracking, and strong impact resistance. The cast steel roll employs monoblock casting process (single pour): Melting-Casting-Heat Treatment-Machining-Flaw Detection-Finished Products. It can be work rolls for blooming and slab mills, section roughing mill rolls, as well as backup rolls for hot-strip steel rolling mills. TINVO's alloy cast steel mill rolls conform to international standards, including ISO, GB, ASTM, DIN, and JIS.

Adamite Roll Introduction The semi-steel adamite roll is casted as a whole and there is no weak interface in compound casting roll, thus it has a better capacity, strength and toughness than cast iron roll. This kind of mill rolls can be used as work roll, back-up roll and vertical roll for large-class and medium-class rough rolling mill and intermediate rolling mill of section steel, wire rod, rail beams, steel billet, hot rolling steel strip. Most of the adamite steel rolls are produced by the static integral casting method. It must be subjected to high-temperature diffusion annealing. Generally, adamite rolls for steel rolling mills are required to control the total amount of non-metallic inclusions below 0.05%. The centrifugal composite semi-steel back-up rolls are made of adamite steel material, the body and neck of the rolls are made of nodular cast iron, and they have been successfully used in hot-rolled strip steel finishing mill.

Forged steel rolls have toughness, surface hardness uniformity and fatigue resistance and widely used to the cold rolling mill. The mill rolls are made from steel ingots by forging. Forging can solve metallurgical defects such as loose and shrinkage holes in the ingot, and crush the coarse cast structure to obtain a high-quality roll with dense structure and uniform composition. The production process of forged roll includes smelting, ingot casting, forging, post-forging heat treatment, rough processing, final heat treatment and finishing. The rolls are heat-treated differently depending on the material and application. They are mainly used as strip rolling mill work roll and backup roll, H-type steel universal–shaft, High-speed roll(HSS roll), Cr4 steel backup roll, Cr5 forged steel roll, 86CrMoV7 forged steel roll, 42CrMo forged steel roll, MC2, MC3, MC5, MC6 forged steel roll, etc.

The cast iron roll is produced by a horizontal centrifugal casting process with high-speed steel as the work layer and nodular iron as the core. The material of centrifugal casting iron roll contains plenty of alloying elements such as Mo, Ni, Cr, etc. The high hardened eutectic carbides & second carbides, evenly distributed in tempered martensitic matrix, make the wear and thermal cracking resistance very excellent. Besides, the resistance to surface roughing is also good. In a condition of hot rolling, the contact points between steel strip and the work rolls can form a thin adherent oxide film on the roll surface, which plays a good role in the wear features and the quality of the strip surface. The main application is as a working roll for hot-rolled strip leveling rack and rack of high-speed wire mill.
