Harbors of steel and electrical facilities are exposed to dust, dirt, corrosive gas while handling large quantities of industrial material such as iron ore and coal. Due to their large scale and high degree of automation, reliability, safety and durability and uptime are a must for any electrical component being used in these applications. From unloading raw materials at harbors to fabricating steel derived products, productivity is the key for these processes which are becoming more automated and operated automatically by computer systems. In contrast, various sensors used in these environments are often damaged.Malfunction of these sensors halt production lines and lower overall productivity.By virtue of its high reliability, Bestact serves as the best solution for sensor application in the fields of steel and cement making plants.
Bestact allows for safe operation of Harbor facilities due to its reliability.
Sinter iron ore and produce sintered ore.
Bake coal in an oven and produce coke.

<< Product Model >>Heavy-duty limit switchPSKU-110R25CB
Harbor facilities incorporate raw material handling machinery such as unloaders and various cranes, reclaimers and stackers for transferring, stacking and discharging iron ore and coal, and belt conveyors arranged in between these machines. Due to their close proximity to coastal areas and their handling of large quantities of industrial materials such as iron ore and coal, the harbor facilities are exposed to an environment where dust, corrosive gas, rain water (muddy water) are commonplace.A Bestact limit switch, PIKU-110R25A-01 is installed on a girder of an unloader in order to prevent an accident that may be caused by an overrun of the crab trolley slipping on the rails. PIKU-110R25A-01 is a vane type limit switch; it is non-contact sensor that avoids the pitfalls associated mechanical contact limit switches and sensors. It has high switching reliability and durability under severe environments.
The Bestact PSKU-110R25CB is used for the reversing of conveyer belt operation and detecting belt derailment, where the dust condition is especially severe even among harbor facilities.

Dust generated from conveying coke and raw materials adheres to conventional switch devices and impairs their ability to operate reliably.
Consequently, industrial engineers crave switches with longer life and without contact problems. Bestact built in limit and proximity switches can meet such demand due to the sealed contact that is used.
During raw material transportation, low-level signals are needed for detecting trolley position
and for opening/closing status of a hopper gate.
Bestact output contacts are used in the master controller in iron making plants.Slide movements of a cam operate conventional contacts. However, the cam often seizes and oxide coating forms on the surface of contacts due to the severe operational environments
and thus causes switching problems of conventional contacts.A Bestact vane type magnetic proximity switch improves reliability of output contacts and mechanical durability of a main operational switch in iron making plants.

PSMS-MV10THA
The frictional heat developed between the “work” rolls of cold strip mill and metal sheet increases the ambient temperature to near 100˚C. In addition to this, lubricant is applied to the sheet metal during this process and creates an environment with high temperature and humidity.
Usage environment
Bestact columnar type magnetic proximity switches are used as sensors for detecting positions of work rolls*1 and winding length of the coil*2 in cold strip mill applications. They exhibit very high reliability and electrical life.
Advantages of Bestact columnar typemagnetic proximity switch
For the galvanization process, Bestact proximity switches are exceptionally suited for harsh conditions such as vapor acid cleaning and oxidization processes.

Coil feeding in hot-dip galvanization process
Hot strip mill is one of the most common facilities in steel fabrication. Each slab is reheated to over 1000˚C in a reheating furnace. It is then run into a hot strip mill set up as a continuous “strip” at speeds of more than 80 km/h where it is f lat-rolled. In a highly automated facility, slabs are run into this mill on the order of every 30 to 45 seconds.
The steel manufacturing industry is on a par with the textile industry in terms of its large consumption of water. Generally speaking, in the fabrication of steel, the blast furnace and hot strip mill will consume the most amount of water.
Also in this process a large amount of rolling oil is mixed with the cooling water and is used to prevent abrasion of the work rolls. In addition to this, various lubricants are applied to the mill stand itself (such as grease for bearings, hydraulic fluid, etc.). Consequently, electrical devices will be exposed to severe heat, humidity, water and oil splash and if one of the electrical components should fail in this application it would be a very costly in terms of lost production.

High Reliability, Inherent in Stringent Quality Control
Bestact products are manufactured in the most advanced facilities, utilizing the expertise we have gained from years of ongoing research and development as well as empirical field data under a stringent quality control system.As example of this would be our production equipment, which automatically adjusts the spring load to the optimum value, thereby maximizing contact life and reliability.

The advantages of conventional auxiliary contacts are electrically and mechanically durable, structurally simple and can be easily maintained. However, after the advent of PLCs, low level signaling (24 VDC, 10 mA) of contactor status became predominant and the use of conventional auxiliary contacts led to contact failure for such signals. Bestact auxiliary contacts are ideally suited for this type of application
due to their wiping action and immunity to the surrounding environment. They have improved reliability significantly.Shown below are examples of applications where Bestact auxiliary contacts are used. Bestact contacts are utilized for auxiliary contacts for circuit breakers and control panels of power distribution devices.
