Heated vessels are also called furnaces. 3.4 centrifugal casting machine machine to manufacture tubes by centrifugal means. The axis of the tube coincides with the axis of rotation and where the thickness of the tube is determined by the dimensions of the mould and the amount of metal cast (see Annex B, Figure B.7). The said axis may be horizontal or oblique (vertical axis of rotation is excluded, see Clause 1) 3.5 continuous and semi continuous casting machine machine which provides a regular or intermittent supply of liquid metal (for this document: non-ferrous metal only, see Clause 1) to a mould, from where the solidified product leaves under gravity or by powered means
Depending upon the direction in which the bar leaves the tundish distinction is made between vertical and horizontal casting. Additionally, distinction is made between continuous and semi continuous casting as to whether the bar is cast without interruption and cut with a flying saw or is stopped after reaching a determined length and is then completely removed from the equipment. In the non-ferrous metals sector the semi continuous casting process is mainly used. 3.6 metering monitoring the amount of liquid metal 3.7 breakthrough refractory lining of the pouring equipment is penetrated by molten metal 3.8 stripping/ejection of castings removal of the centrifugal casting from the mould after solidification ! 3.9 dynamically self-locking a gearbox meets the requirements for dynamically self-locking, if the geared motor drive stops immediately or after a short time after switch-off even if a torque is acting at the output side of the gearbox NOTE Dynamic automatic locking is only possible at very high transmissions ratios and in low drive speed ranges."

 Disintegration of parts of the die due to centrifugal force, e. g., die-lockings.  Strength of the die and die-locking. D  Information for use shall provide instructions of intended use, e.g.,  speed limits (rpm) corresponding to the strength of the die and  pressure limits. V, D
 Uncontrolled over-speed of the drive (electronic controlled)  Limiting of the speed (rpm) by proximity switches. D
 Mechanical rail guided cross transport of castings.  Design equipment to prevent trapping of persons so that movements of the equip-ment do not cause danger. D SIST EN 1247:2004+A1:2010

 Dies moving along pouring spouts and approaching end stops.  Provide safety distances by location of parts, according to EN 349. V, D, M
 Ejection or falling of the die from the bearing rollers.  Design to prevent ejection or falling of die (see Annex B, Figure B.8), e. g.  fixed guides;  restraining pieces. D 5.4.2 Burns, impact, crushing  Machine integrated controlled tilting of the ladle, manually initiated.  The tilting movement shall be activated only when energised through a hold-to-run control device, placed where its operator has a full and unrestricted view of the ladle and the receiver vessel/container. D 5.4.3 Burns  Discharge of molten metal due to  disintegration of parts (see also 5.4.1);  unintended loosening of die-lockings during rotation of the die;  unintended machine stop Centrifugally applied die-lockings shall be designed to prevent them loosening during casting operation. Die-lockings that are actuated pneumatically, hydraulically or electro-mechanically shall be designed in such a way that unlocking cannot occur before the solidification of the liquid metal. D
 The emergency stop device for the die rotation movement (see 5.4.9) shall correspond to 9.2.2 of
!EN 60204-1:2006", !stop category 1", and !EN ISO 13850". D, F
 Shifting of movable and slew-able pouring spouts.  It shall be possible to fix pouring spouts positively prior to start of casting operation, e. g., by locking clamps. V, D, F
 Ejecting metal during rotation of the die.  Coverings to protect against burns caused by ejection of molten metal shall be included and conformed to fixed guard (see 5.3.2.1 of EN ISO 12100-2:2003 and EN 953) with an inserted movable guard (see 5.3.2.3 of EN ISO 12100-2:2003, EN 953 and EN 1088). V, D 5.4.4 Fire, burns  Uncontrolled release and igni-tion of hydraulic fluids  Pipework and hoses for hydraulic fluids shall be protected against mechanical and thermal damage by the use of covers, shielding etc. and fixing means such as ducts and channels and V, D
 Hydraulic equipment shall be suitable for use with fire resistant hydraulic fluids (see ISO 7745 and Annex A) and V, D SIST EN 1247:2004+A1:2010

 Information for use shall include advice, that hydraulic fluids which contain poly-chlorinated bi phenyls (P.C.B.) and poly-chlorinated tri phenyls (P.C.T.) shall not be used (see !7.4.2"). V, D 5.4.5 Noise  Noise during operation.  Noise reduction by design
